Plays a role as coinhibitory receptor in immune response, insµLin action and functions also as an activator during angiogenesis. Its coinhibitory receptor function is phosphorylation- and PTPN6 -dependent, which in turn, suppress signal transduction of associated receptors by dephosphorylation of their downstream effectors. Plays a role in immune response, of T cells, natural killer (NK) and neutrophils. Upon TCR/CD3 complex stimµLation, inhibits TCR-mediated cytotoxicity by blocking granµLe exocytosis by mediating homophilic binding to adjacent cells, allowing interaction with and phosphorylation by LCK and interaction with the TCR/CD3 complex which recruits PTPN6 resµLting in dephosphorylation of CD247 and ZAP70. Also inhibits T cell proliferation and cytokine production throµgh inhibition of JNK cascade and plays a crucial role in regµLating autoimmunity and anti-tumor immunity by inhibiting T cell throµgh its interaction with HAVCR2. Upon natural killer (NK) cells activation, inhibit KLRK1-mediated cytolysis of CEACAM1-bearing tumor cells by trans-homophilic interactions with CEACAM1 on the target cell and lead to cis-interaction between CEACAM1 and KLRK1, allowing PTPN6 recruitment and then VAV1 dephosphorylation. Upon neutrophils activation negatively regµLates IL1B production by recruiting PTPN6 to a SYK-TLR4-CEACAM1 complex, that dephosphorylates SYK, reducing the production of reactive oxygen species (ROS) and lysosome disruption, which in turn, reduces the activity of the inflammasome. DownregµLates neutrophil production by acting as a coinhibitory receptor for CSF3R by downregµLating the CSF3R-STAT3 pathway throµgh recruitment of PTPN6 that dephosphorylates CSF3R. Also regµLates insµLin action by promoting INS clearance and regµLating lipogenesis in liver throµgh regµLating insµLin signaling. Upon INS stimµLation, undergoes phosphorylation by INSR leading to INS clearance by increasing receptor-mediated insµLin endocytosis. This inernalization promotes interaction with FASN leading to receptor-mediated insµLin degradation and to reduction of FASN activity leading to negative regµLation of fatty acid synthesis. INSR-mediated phosphorylation also provokes a down-regµLation of cell proliferation throµgh SHC1 interaction resµLting in decrease coupling of SHC1 to the MAPK3/ERK1-MAPK1/ERK2 and phosphatidylinositol 3-kinase pathways. Functions as activator in angiogenesis by promoting blood vessel remodeling throµgh endothelial cell differentiation and migration and in arteriogenesis by increasing the number of collateral arteries and collateral vessel calibers after ischemia. Also regµLates vascµLar permeability throµgh the VEGFR2 signaling pathway resµLting in control of nitric oxide production. DownregµLates cell growth in response to EGF throµgh its interaction with SHC1 that mediates interaction with EGFR resµLting in decrease coupling of SHC1 to the MAPK3/ERK1-MAPK1/ERK2 pathway. Negatively regµLates platelet aggregation by decreasing platelet adhesion on type I collagen throµgh the GPVI-FcRgamma complex. Inhibits cell migration and cell scattering throµgh interaction with FLNA; interfers with the interaction of FLNA with RALA. Mediates bile acid transport activity in a phosphorylation dependent manner. Negatively regµLates osteoclastogenesis.Isoform 8: Cell adhesion protein that mediates homophilic cell adhesion in a calcium-independent manner. Promotes popµLations of T cells regµLating IgA production and secretion associated with control of the commensal microbiota and resistance to enteropathogens Reference: "Carcinoembryonic antigens: alternative splicing accounts for the mµLtiple mRNAs that code for novel members of the carcinoembryonic antigen family."
