Anti-PVRL4/NECTIN4 Antibody Picoband® Fluoro594 Conjugated

PVRL4, also known as Nectin-4, is expressed in human skin, hair follicles, and cultured keratinocytes, but not in fibroblasts. This gene encodes a member of the nectin family. The encoded protein contains two immunoglobulin-like (Ig-like) C2-type domains and one Ig-like V-type domain. It is involved in cell adhesion through trans-homophilic and -heterophilic interactions. It is a single-pass type I membrane protein. The soluble form is produced by proteolytic cleavage at the cell surface by the metalloproteinase ADAM17/TACE. The secreted form is found in both breast tumor cell lines and breast tumor patients. Mutations in this gene are the cause of ectodermal dysplasia-syndactyly syndrome type 1, an autosomal recessive disorder. Alternatively spliced transcript variants have been found but the full-length nature of the variant has not been determined.

Nectin-4; Ig superfamily receptor LNIR; Nectin cell adhesion molecule 4 ; Poliovirus receptor-related protein 4; Processed poliovirus receptor-related protein 4; NECTIN4 ; LNIR, PRR4, PVRL4

A synthetic peptide corresponding to a sequence at the N-terminus of human Nectin-4/PVRL4, different from the related mouse sequence by seven amino acids.

Seems to be involved in cell adhesion through trans- homophilic and -heterophilic interactions, the latter including specifically interactions with NECTIN1. Does not act as receptor for alpha-herpesvirus entry into cells.
