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.

Product Specifications

Recombinant Human Spermatogenesis-defective protein 39 homolog (SPE39) is a recombinant protein, expressed in E.coli, covering amino acids 1-493aa, with N-terminal 6xHis-SUMO-tagged tag, molecular weight 73.0kDa, purity Greater than 90% as determined by SDS-PAGE..
