Human CUB Domain Containing Protein 1 (CDCP1) Protein

Background

CDCP1 (CUB Domain Containing Protein 1), also known as CD318 or Trask, is a transmembrane protein widely expressed across cell types, including epithelial cells, stem cells, and notably in certain types of cancer cells. CDCP1 is known for its involvement in various cellular processes, including cell adhesion, migration, and signal transduction. It is a single-pass membrane protein characterized by extracellular CUB domains, which are implicated in protein-protein interactions, especially in cell communication and adhesion mechanisms. CDCP1 plays a crucial role in cancer biology, as its overexpression or aberrant activation has been observed in multiple malignancies, such as lung, colon, and breast cancer, where it contributes to processes like invasion, metastasis, and resistance to apoptosis. This makes CDCP1 an important molecule in cancer progression and a potential target for therapeutic interventions. Moreover, CDCP1 is implicated in non-cancerous biological pathways, including wound healing and tissue remodeling, which involve dynamic changes in cell adhesion and migration.
