Protein function

Binds to and inhibits the transcriptional repressor ZBTB33, which may lead to activation of target genes of the Wnt signaling pathway (By similarity). Associates with and regulates the cell adhesion properties of both C-, E- and N-cadherins, being critical for their surface stability. Implicated both in cell transformation by SRC and in ligand-induced receptor signaling through the EGF, PDGF, CSF-1 and ERBB2 receptors. Promotes GLIS2 C-terminal cleavage.

Protein tissue specificity

Expressed in vascular endothelium. Melanocytes and melanoma cells primarily express the long isoform 1A, whereas keratinocytes express shorter isoforms, especially 3A. The shortest isoform 4A, is detected in normal keratinocytes and melanocytes, and generally lost from cells derived from squamous cell carcinomas or melanomas. The C-terminal alternatively spliced exon B is present in the p120ctn transcripts in the colon, intestine and prostate, but lost in several tumor tissues derived from these organs.

Protein sequence and domain

A possible nuclear localization signal exists in all isoforms where Asp-626–631-Arg are deleted.; ARM repeats 1 to 5 mediate interaction with cadherins.Belongs to the beta-catenin family.; Contains 10 ARM repeats.

Protein post-translational modifications

Phosphorylated by FER and other protein-tyrosine kinases. Phosphorylated at Ser-288 by PAK7/PAK5. Dephosphorylated by PTPRJ.

Protein cellular localization

Cytoplasm. Nucleus. Cell membrane. Note: Interaction with GLIS2 promotes nuclear translocation (By similarity). Detected at cell-cell contacts. NANOS1 induces its translocation from sites of cell-cell contact to the cytoplasm. Isoforms 4A and 1AB are excluded from the nucleus.; Isoform 1A: Nucleus.; Isoform 2A: Nucleus.; Isoform 3A: Nucleus.


Catenin delta-1 (p120 catenin) has an amino-terminal coiled-coil domain followed by a regulatory domain containing multiple phosphorylation sites and a central Armadillo repeat domain of ten linked 42-amino acid repeats. The carboxy-terminal tail has no known function (1). Catenin delta-1 fulfills critical roles in the regulation of cell-cell adhesion as it regulates E-cadherin turnover at the cell surface to determine the level of E-cadherin available for cell-cell adhesion (2). Catenin delta-1 has both positive and negative effects on cadherin-mediated adhesion (3). Actin dynamics are also regulated by catenin delta-1, which modulates RhoA, Rac, and cdc42 proteins (1). Analogous to beta-catenin, catenin delta-1 translocates to the nucleus, although its role at this location is unclear. Many studies show that catenin delta-1 is expressed irregularly or is absent in various types of tumor cells, suggesting that catenin delta-1 may function as a tumor suppressor (4).Phosphorylation of Tyr904 on Catenin-delta-1 was identified at Cell Signaling Technology (CST) using PhosphoScan®, a CST’s LC-MS/MS platform for phosphorylation site discovery (5).
