CD44 (CD44 antigen) is a gene. The public catalogues list it as a drug target and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. Tied to Gastric & gastro-oesophageal junction cancer, Ovarian cancer, Colorectal cancer and 5 more. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Cell-surface receptor that plays a role in cell-cell interactions, cell adhesion and migration, helping them to sense and respond to changes in the tissue microenvironment. Participates thereby in a wide variety of cellular functions including the activation, recirculation and homing of T-lymphocytes, haematopoiesis, inflammation and response to bacterial infection. Engages, through its ectodomain, extracellular matrix components such as hyaluronan/HA, collagen, growth factors, cytokines or proteases and serves as a platform for signal transduction by assembling, via its cytoplasmic domain, protein complexes containing receptor kinases and membrane proteases. Such effectors include PKN2, the RhoGTPases RAC1 and RHOA, Rho-kinases and phospholipase C that coordinate signalling pathways promoting calcium mobilisation and actin-mediated cytoskeleton reorganisation essential for cell migration and adhesion. Upon interaction with LGALS9 ligand, activates downstream signalling components including LCK, ERK and MAPK to promotes NK cell activation. Location: Cell membrane; Cell projection, microvillus; Secreted (UniProt). Locus 11p13 (HGNC).
