Facts about Spermatogenesis-defective protein 39 homolog.
May play a role in lysosomal trafficking, probably via association with the core HOPS complex at a different population of endosomes; the acts seems to be indepenedent of VPS33B (PubMed:19109425). May play a role in vesicular trafficking through spermatogenesis (By similarity).
