The cancer tissues expressed weak to moderate cytoplasmic staining. Strong immunoreactivity was seen in
several cases of melanomas, endometrial cancers, urothelial cancers and renal cancers.
Most cancers showed a staining pattern similar to that seen in normal cells, weak to moderate cytoplasmic positivity. Membranous staining was mainly seen in adenocarcinomas. Lymphomas were either weakly stained in cytoplasm or were negative.
This gene encodes a member of the nectin family of proteins, which function as adhesion molecules at adherens junctions. This family member interacts with other nectin-like proteins and with afadin, a filamentous actin-binding protein involved in the regulation of directional motility, cell proliferation and survival. This gene plays a role in ocular development involving the ciliary body. Mutations in this gene are believed to result in congenital ocular defects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]
