PVRL4 ELISA 试剂盒

Tissue Specificity: Predominantly expressed in placenta. Not detected in normal breast epithelium but expressed in breast carcinoma. .

Protein Function: 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.

Background: Nectin-4, also known as PVRL4, is an adhesion receptor of the immunoglobulin superfamily and functions in cell-cell adhesion. This gene is mapped to chromosome 1q23.3. 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.
