p23_hB-ind1_like cd06465
p23_like domain found in human (h) butyrate-induced transcript 1 (B-ind1) and similar proteins. ...
 7-128 1.87e-38

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.

 11-107 2.29e-08

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.
