Recombinant Human Spermatogenesis-defective protein 39 homolog (SPE39)

Uniprot Id

Q9H9C1

Target Species

Human

Target Name

VIPAS39

Target Full Name

Spermatogenesis-defective protein 39 homolog

Target Function

Proposed to be involved in endosomal maturation implicating in part VPS33B. In epithelial cells, the VPS33B:VIPAS39 complex may play a role in the apical RAB11A-dependent recycling pathway and in the maintenance of the apical-basolateral polarity. May play a role in lysosomal trafficking, probably via association with the core HOPS complex in a discrete population of endosomes; the functions seems to be independent of VPS33B. May play a role in vesicular trafficking during spermatogenesis. May be involved in direct or indirect transcriptional regulation of E-cadherin.

Target Involvement

Arthrogryposis, renal dysfunction and cholestasis syndrome 2 (ARCS2)

Target Subcellular Location

Cytoplasm. Cytoplasmic vesicle. Early endosome. Recycling endosome. Late endosome. Note=Colocalizes in clusters with VPS33B at cytoplasmic organelles (PubMed:19109425).
