FYVE-related domain found in Slp homolog lacking C2 domains a (SlaC2-a) and similar proteins; SlaC2-a, also termed melanophilin, or exophilin-3, is a GTP-bound form of Rab27A-, myosin Va-, and actin-binding protein present on melanosomes. It is involved in the control of transferring of melanosomes from microtubules to actin filaments. It also functions as a melanocyte type myosin Va (McM5) binding partner and directly activates the actin-activated ATPase activity of McM5 through forming a tripartite protein complex with Rab27A and an actin-based motor myosin Va. SlaC2-a belongs to the Slp homolog lacking C2 domains (Slac2) family. It contains an N-terminal Slp homology domain (SHD), but lacks tandem C2 domains. The SHD consists of two conserved regions, designated SHD1 (Slp homology domain 1) and SHD2, which may function as protein interaction sites. The SHD1 and SHD2 of SlaC2-a are separated by a putative FYVE zinc finger, which resembles a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif. Moreover, Slac2-a has a middle myosin-binding domain and a C-terminal actin-binding domain. Pssm-ID: 277291 Cd Length: 76 Bit Score: 153.80 E-value: 4.85e-45

FYVE-related domain found in the synaptotagmin-like proteins 3, 4, 5; The synaptotagmin-like proteins 1-5 (Slp1-5) family belongs to the carboxyl-terminal-type (C-type) tandem C2 proteins superfamily, which also contains the synaptotagmin and the Doc2 families. Slp proteins are putative membrane trafficking proteins that are characterized by the presence of a unique N-terminal Slp homology domain (SHD), and C-terminal tandem C2 domains (known as the C2A domain and C2B domain). The SHD consists of two conserved regions, designated SHD1 (Slp homology domain 1) and SHD2. The SHD1 and SHD2 of Slp3, Slp4 and Slp5 are separated by a putative FYVE zinc finger. By contrast, Slp1 and Slp2 lack such zinc finger and their SHD1 and SHD2 are linked together. This model corresponds to the FYVE zinc finger. At this point, Slp1 and Slp2 are not included in this model. Moreover, the FYVE domains of Slp3, Slp4 and Slp5 resemble a FYVE-related domain that is structurally similar to the canonical FYVE domains but lacks the three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif.

FYVE domain like superfamily; FYVE domain is a 60-80 residue double zinc finger motif-containing module named after the four proteins, Fab1, YOTB, Vac1, and EEA1. The canonical FYVE domains are distinguished from other zinc fingers by three signature sequences: an N-terminal WxxD motif (x for any residue), the central basic R(R/K)HHCRxCG patch, and a C-terminal RVC motif, which form a compact phosphatidylinositol 3-phosphate (PtdIns3P, also termed PI3P)-binding site. They are found in many membrane trafficking regulators, including EEA1, Hrs, Vac1p, Vps27p, and FENS-1, which locate to early endosomes, specifically bind PtdIns3P, and play important roles in vesicular traffic and in signal transduction. Some proteins, such as rabphilin-3A and alpha-Rab3-interacting molecules (RIMs), are also involved in membrane trafficking and bind to members of the Rab subfamily of GTP hydrolases. However, they contain FYVE-related domains that are structurally similar to the canonical FYVE domains but lack the three signature sequences. At this point, they may not bind to phosphoinositides. In addition, this superfamily also contains the third group of proteins, caspase-associated ring proteins CARP1 and CARP2. They do not localize to membranes in the cell and are involved in the negative regulation of apoptosis, specifically targeting two initiator caspases, caspase 8 and caspase 10, which are distinguished from other FYVE-type proteins. Moreover, these proteins have an altered sequence in the basic ligand binding patch and lack the WxxD motif that is conserved only in phosphoinositide binding FYVE domains. Thus they constitute a family of unique FYVE-type domains called FYVE-like domains. The FYVE domain is structurally similar to the RING domain and the PHD finger. This superfamily also includes ADDz zinc finger domain, which is a PHD-like zinc finger motif that contains two parts, a C2-C2 and a PHD-like zinc finger.

FYVE-related domain found in synaptotagmin-like protein 3 (Slp3) and similar proteins; Slp3, also termed exophilin-6, functions as a Rab27A-specific effector in cytotoxic T lymphocytes. It binds to kinesin-1 motor through interaction with the tetratricopeptide repeat of the kinesin-1 light chain (KLC1). The kinesin-1/Slp3/Rab27a complex plays a role in mediating the terminal transport of lytic granules to the immune synapse.

It can binds to syntaxin 2 in parotid acinar cells. It is also involved in granule transport by recruitment of the motor protein myosin Va. Moreover, it requires Rab8 to increase granule release in platelets. Slp4 contains an N-terminal Slp homology domain (SHD) and C-terminal tandem C2 domains.
