CC -!- FUNCTION: Cell-surface receptor that plays a role in cell-cell CC interactions, cell adhesion and migration, helping them to sense and CC respond to changes in the tissue microenvironment (PubMed:16541107, CC PubMed:19703720, PubMed:22726066). Participates thereby in a wide CC variety of cellular functions including the activation, recirculation CC and homing of T-lymphocytes, hematopoiesis, inflammation and response CC to bacterial infection (PubMed:7528188). Engages, through its CC ectodomain, extracellular matrix components such as hyaluronan/HA, CC collagen, growth factors, cytokines or proteases and serves as a CC platform for signal transduction by assembling, via its cytoplasmic CC domain, protein complexes containing receptor kinases and membrane CC proteases (PubMed:18757307, PubMed:23589287). Such effectors include CC PKN2, the RhoGTPases RAC1 and RHOA, Rho-kinases and phospholipase C CC that coordinate signaling pathways promoting calcium mobilization and CC actin-mediated cytoskeleton reorganization essential for cell migration CC and adhesion (PubMed:15123640). {ECO:0000269|PubMed:15123640, CC ECO:0000269|PubMed:16541107, ECO:0000269|PubMed:18757307, CC ECO:0000269|PubMed:19703720, ECO:0000269|PubMed:22726066, CC ECO:0000269|PubMed:23589287, ECO:0000269|PubMed:7528188}.

CC Interacts with UNC119 (PubMed:19381274). Interacts with PDPN (via CC extracellular domain); this interaction is required for PDPN-mediated CC directional migration and regulation of lamellipodia CC extension/stabilization during cell spreading and migration CC (PubMed:20962267). Interacts with RDX, EZR and MSN (By similarity). CC Interacts with EGFR (PubMed:18757307, PubMed:23589287).

Additional isoforms are CC produced by alternative splicing of 10 out of 19 exons within the CC extracellular domain. Additional diversity is generated through the CC utilization of internal splice donor and acceptor sites within 2 of CC the exons. A variation in the cytoplasmic domain was shown to result CC from the alternative splicing of 2 exons. Isoform CD44 is expected to CC be expressed in normal cells. Splice variants have been found in many CC tumor cell lines. Exons 5, 6, 7, 8, 9, 10, 11, 13, 14 and 19 are CC alternatively spliced. Experimental confirmation may be lacking for CC some isoforms. {ECO:0000269|PubMed:1465456}; CC Name=1; Synonyms=CD44; CC IsoId=P16070-1; Sequence=Displayed; CC Name=2; Synonyms=CD44SP; CC IsoId=P16070-2; Sequence=VSP_005303, VSP_005304; CC Name=3; CC IsoId=P16070-3; Sequence=VSP_005305, VSP_005306; CC Name=4; Synonyms=Epidermal; CC IsoId=P16070-4; Sequence=VSP_005307, VSP_005308; CC Name=5; CC IsoId=P16070-5; Sequence=VSP_005313; CC Name=6; CC IsoId=P16070-6; Sequence=VSP_005314, VSP_005315; CC Name=7; CC IsoId=P16070-7; Sequence=VSP_005316, VSP_005317; CC Name=8; CC IsoId=P16070-8; Sequence=VSP_005318, VSP_005319; CC Name=9; CC IsoId=P16070-9; Sequence=VSP_005320, VSP_005321; CC Name=10; Synonyms=CD44E, CD44R1, Epithelial, Keratinocyte; CC IsoId=P16070-10; Sequence=VSP_005309, VSP_005310; CC Name=11; Synonyms=CD44R2; CC IsoId=P16070-11; Sequence=VSP_022797; CC Name=12; Synonyms=CDw44, Reticulocyte; CC IsoId=P16070-12; Sequence=VSP_005311, VSP_005312; CC Name=13; Synonyms=CD44R4; CC IsoId=P16070-13; Sequence=VSP_005309, VSP_005310, VSP_005318, CC VSP_005319; CC Name=14; Synonyms=CD44R5; CC IsoId=P16070-14; Sequence=VSP_005309, VSP_005310, VSP_005316, CC VSP_005317, VSP_005318, VSP_005319; CC Name=15; Synonyms=Hermes; CC IsoId=P16070-15; Sequence=VSP_005311, VSP_005312, VSP_005320, CC VSP_005321; CC Name=16; CC IsoId=P16070-16; Sequence=VSP_005305, VSP_005306, VSP_005314, CC VSP_005315; CC Name=17; CC IsoId=P16070-17; Sequence=VSP_005313, VSP_005314, VSP_005315; CC Name=18; CC IsoId=P16070-18; Sequence=VSP_005311, VSP_005312, VSP_043575; CC Name=19; Synonyms=CD44RC; CC IsoId=P16070-19; Sequence=VSP_043870, VSP_043871; CC -!- TISSUE SPECIFICITY: Detected in fibroblasts and urine (at protein CC level) (PubMed:25326458, PubMed:36213313, PubMed:37453717).
