Generic protein structure example

p120, and called catenin delta-1 is a protein that in humans is encoded by the CTNND1 gene.[1]

Function

This gene encodes a member of the Armadillo protein family, which function in adhesion between cells and signal transduction. Multiple translation initiation codons and alternative splicing result in many different isoforms being translated. Not all of the full-length natures of the described transcript variants have been determined.[2]

Clinical significance

Immunohistochemistry for p120 has cytoplasmic staining in invasive lobular carcinoma (shown), but has membranous staining in invasive ductal carcinoma, thereby helping to distinguish these cancer types.

Either loss or cytoplasmic localization of p120 is a common feature in the progression of several types of carcinoma.[3]

Interactions

CTNND1 has been shown to interact with:
