Phospho-CDCP1 (Tyr743)

CDCP1 (CUB Domain Containing Protein 1) is a Protein Coding gene. Diseases associated with CDCP1 include Colorectal Cancer. Among its related pathways are Wnt / Hedgehog / Notch and NF-kappaB Signaling.

Full Name

CUB Domain Containing Protein 1

Function

May be involved in cell adhesion and cell matrix association. May play a role in the regulation of anchorage versus migration or proliferation versus differentiation via its phosphorylation. May be a novel marker for leukemia diagnosis and for immature hematopoietic stem cell subsets. Belongs to the tetraspanin web involved in tumor progression and metastasis.

Cellular Location

Isoform 1: Cell membrane. Shedding may also lead to a soluble peptide.
Isoform 3: Secreted

Topology

Extracellular: 30-667
Helical: 668-688
Cytoplasmic: 689-836

PTM

Phosphorylated on tyrosine by kinases of the SRC family such as SRC and YES as well as by the protein kinase C gamma/PRKCG. Dephosphorylated by phosphotyrosine phosphatases. Also phosphorylated by suramin, a heparin analog. Tyrosine phosphorylated in response to dissociation of integrin alpha-6 beta-4 from laminin-5.
N-glycosylated.
A soluble form may also be produced by proteolytic cleavage at the cell surface (shedding). Another peptide of 80 kDa (p80) is present in cultured keratinocytes probably due to tryptic cleavage at an unidentified site on its N-terminal side. Converted to p80 by plasmin, a trypsin-like protease.
