Most cancer tissues showed weak to moderate cytoplasmic positivity. Few squamous cell carcinomas of skin, uterine cervix, urothelium and malignant melanomas displayed strong immunoreactivity. Several liver, lung, endometrium and a few kidney, stomach, pancreas and testis cancers were negative.
Strong cytoplasmic immunoreactivity with a granular pattern was displayed in most cancer tissues. Few cases of renal cancers were weakly stained.

Description
Vacuolar protein sorting 16 homolog (S. cerevisiae) (HGNC Symbol)
Entrez gene summary
Vesicle mediated protein sorting plays an important role in segregation of intracellular molecules into distinct organelles. Genetic studies in yeast have identified more than 40 vacuolar protein sorting (VPS) genes involved in vesicle transport to vacuoles. This gene encodes the human homolog of yeast class C Vps16 protein. The mammalian class C Vps proteins are predominantly associated with late endosomes/lysosomes, and like their yeast counterparts, may mediate vesicle trafficking steps in the endosome/lysosome pathway. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2009]
