6-84 | 3.07e-23 | ||||
p23_like domain similar to the C-terminal CHORD-SGT1 (CS) domain of Sgt1 (suppressor of G2 allele of Skp1). Sgt1 interacts with multiple protein complexes and has the features of a cochaperone. Human (h) Sgt1 interacts with both Hsp70 and Hsp90, and has been shown to bind Hsp90 through its CS domain. Saccharomyces cerevisiae (Sc) Sgt1 is a subunit of both core kinetochore and SCF (Skp1-Cul1-F-box) ubiquitin ligase complexes. Sgt1 is required for pathogen resistance in plants. ScSgt1 is needed for the G1/S and G2/M cell-cycle transitions, and for assembly of the core kinetochore complex (CBF3) via activation of Ctf13, the F-box protein. Binding of Hsp82 (a yeast Hsp90 homologue) to ScSgt1, promotes the binding of Sgt1 to Skp1 and of Skp1 to Ctf13. Some proteins in this group have an SGT1-specific (SGS) domain at the extreme C-terminus. The ScSgt1-SGS domain binds adenylate cyclase. The hSgt1-SGS domain interacts with some S100 family proteins, and studies suggest that the interaction of hSgt1 with Hsp90 and Hsp70 may be regulated by S100A6 in a Ca2+ dependent fashion. This group also includes the p23_like domains of Melusin and NAD(P)H cytochrome b5 (NCB5) oxidoreductase (OR). Melusin is a vertebrate protein which interacts with two splice variants of beta1 integrin, and NCB5OR plays a part in maintaining viable pancreatic beta cells.

6-84 | 1.12e-22 | ||||
p23_like domain similar to the C-terminal CS (CHORD-SGT1) domain of human (h) Sgt1 and related proteins. hSgt1 is a co-chaperone which has been shown to be elevated in HEp-2 cells as a result of stress conditions such as heat shock. It interacts with the heat shock proteins (HSPs) Hsp70 and Hsp90, and it expression pattern is synchronized with these two Hsps. The interaction with HSP90 has been shown to involve the hSgt1_CS domain, and appears to be required for correct kinetochore assembly and efficient cell division. Some proteins in this subgroup contain a tetratricopeptide repeat (TPR) HSP-binding domain N-terminal to this CS domain, and most proteins in this subgroup contain a Sgt1-specific (SGS) domain C-terminal to the CS domain. The SGS domain interacts with some S100 family proteins. Studies suggest that S100A6 modulates in a Ca2+ dependent manner the interactions of hSgt1 with Hsp90 and Hsp70. The yeast Sgt1 CS domain is not found in this subgroup. Pssm-ID: 107239 Cd Length: 84 Bit Score: 86.28 E-value: 1.12e-22

Proteins containing this p23_like domain include p23 and its Saccharomyces cerevisiae (Sc) homolog Sba1. Both are co-chaperones for the heat shock protein (Hsp) 90. p23 binds Hsp90 and participates in the folding of a number of Hsp90 clients, including the progesterone receptor. p23 also has a passive chaperoning activity and in addition may participate in prostaglandin synthesis. Both p23 and Sba1p can regulate telomerase activity. This group includes domains similar to the C-terminal CHORD-SGT1 (CS) domain of suppressor of G2 allele of Skp1 (Sgt1). Sgt1 interacts with multiple protein complexes and has the features of a co-chaperone. Human (h) Sgt1 interacts with both Hsp70 and Hsp90, and has been shown to bind Hsp90 through its CS domain. Saccharomyces cerevisiae (Sc) Sgt1 is a subunit of both core kinetochore and SCF (Skp1-Cul1-F-box) ubiquitin ligase complexes. Sgt1 is required for pathogen resistance in plants. This group also includes the p23_like domains of human butyrate-induced transcript 1 (hB-ind1), NUD (nuclear distribution) C, Melusin, and NAD(P)H cytochrome b5 (NCB5) oxidoreductase (OR). hB-ind1 plays a role in the signaling pathway mediated by the small GTPase Rac1, NUDC is needed for nuclear movement, Melusin interacts with two splice variants of beta1 integrin, and NCB5OR plays a part in maintaining viable pancreatic beta cells.

CS domain; The CS and CHORD (pfam04968) are fused into a single polypeptide chain in metazoans but are found in separate proteins in plants; this is thought to be indicative of an interaction between CS and CHORD. It has been suggested that the CS domain is a binding module for HSP90, implying that CS domain-containing proteins are involved in recruiting heat shock proteins to multiprotein assemblies. Two CS domains are found at the N-terminus of Ubiquitin carboxyl-terminal hydrolase 19 (USP19), these domains may play a role in the interaction of USP19 with cellular inhibitor of apoptosis 2.

3-84 | 8.32e-13 | ||||
p23_like domain similar to the C-terminal (tail) domain of vertebrate Melusin and related proteins. Melusin's tail domain interacts with the cytoplasmic domain of beta1-A and beta1-D isoforms of beta1 integrin, it does not bind other integrin beta subunits. Melusin is a muscle-specific protein expressed in skeletal and cardiac muscles but not in smooth muscle or other tissues. It is needed for heart hypertrophy following mechanical overload. The integrin-binding portion of this domain appears to be sequestered in the full length melusin protein, Ca2+ may modulate the protein's conformation exposing this binding site. This group includes Chordc1, also known as Chp-1, which is conserved from vertebrates to humans. Mammalian Chordc1 interacts with the heat shock protein (HSP) Hsp90 and is implicated in circadian and/or homeostatic mechanisms in the brain. The N-terminal portions of proteins belonging to this group contain two cysteine and histidine rich domain (CHORD) domains. Pssm-ID: 107238 Cd Length: 87 Bit Score: 60.77 E-value: 8.32e-13

p23_like domain found in human (h) butyrate-induced transcript 1 (B-ind1) and similar proteins. hB-ind1 participates in signaling by the small GTPase Rac1. It binds to Rac1 and enhances different Rac1 effects including activation of nuclear factor (NF) kappaB and activation of c-Jun N-terminal kinase (JNK). hB-ind1 also plays a part in the RNA replication and particle production of Hepatitis C virus (HCV) through its interaction with heat shock protein Hsp90, HCV nonstructural protein 5A (NS5A), and the immunophilin FKBP8. hB-ind1 is upregulated in the outer layer of Chinese hamster V79 cells grown as multicell spheroids, versus in the same cells grown as monolayers. This group includes the Saccharomyces cerevisiae Sba1, a co-chaperone of the Hsp90. Sba1 has been shown to be is required for telomere length maintenance, and may modulate telomerase DNA-binding activity.

7-74 | 5.73e-06 | ||||
This domain family includes the alpha-crystallin domain (ACD) of alpha-crystallin-type small heat shock proteins (sHsps) and a similar domain found in p23-like proteins. sHsps are small stress induced proteins with monomeric masses between 12 -43 kDa, whose common feature is this ACD. sHsps are generally active as large oligomers consisting of multiple subunits, and are believed to be ATP-independent chaperones that prevent aggregation and are important in refolding in combination with other Hsps. p23 is a cochaperone of the Hsp90 chaperoning pathway. It binds Hsp90 and participates in the folding of a number of Hsp90 clients including the progesterone receptor. p23 also has a passive chaperoning activity. p23 in addition may act as the cytosolic prostaglandin E2 synthase. Included in this family is the p23-like C-terminal CHORD-SGT1 (CS) domain of suppressor of G2 allele of Skp1 (Sgt1) and the p23-like domains of human butyrate-induced transcript 1 (hB-ind1), NUD (nuclear distribution) C, Melusin, and NAD(P)H cytochrome b5 (NCB5) oxidoreductase (OR).

7-84 | 3.58e-05 | ||||
p23_like domain found in proteins similar to dyslexia susceptibility 1 (DYX1) candidate 1 (C1) protein, DYX1C1. The human gene encoding this protein is a positional candidate gene for developmental dyslexia (DD), it is located on 15q21.3 by the DYX1 DD susceptibility locus (15q15-21). Independent association studies have reported conflicting results. However, association of short-term memory, which plays a role in DD, with a variant within the DYX1C1 gene has been reported. Most proteins belonging to this group contain a C-terminal tetratricopeptide repeat (TPR) protein binding region. Pssm-ID: 107226 Cd Length: 78 Bit Score: 40.33 E-value: 3.58e-05

5-84 | 3.95e-04 | ||||
p23_like domain found in proteins similar to Calcyclin-Binding Protein(CacyBP)/Siah-1-interacting protein (SIP). CacyBP/SIP interacts with S100A6 (calcyclin), with some other members of the S100 family, with tubulin, and with Siah-1 and Skp-1. The latter two are components of the ubiquitin ligase that regulates beta-catenin degradation. The beta-catenin gene is an oncogene participating in tumorigenesis in many different cancers. Overexpression of CacyBP/SIP, in part through its effect on the expression of beta-catenin, inhibits the proliferation, tumorigenicity, and invasion of gastric cancer cells. CacyBP/SIP is abundant in neurons and neuroblastoma NB2a cells. An extensive re-organization of microtubules accompanies the differentiation of NB2a cells. CacyBP/SIP may contribute to NB2a cell differentiation through binding to and increasing the oligomerization of tubulin. CacyBP/SIP is also implicated in differentiation of erythroid cells, rat neonatal cardiomyocytes, in mouse endometrial events, and in thymocyte development.
