This gene encodes the iota polypeptide chain that is associated with the Ig-mu chain to form a molecular complex which is expressed on the surface of pre-B cells. The complex is thought to regulate Ig gene rearrangements in the early steps of B-cell differentiation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2015]. * **UniProt Summary**: Associates with the Ig-mu chain to form a molecular complex that is expressed on the surface of pre-B-cells. This complex presumably regulates Ig gene rearrangements in the early steps of B-cell differentiation. |V-set| |immunoglobulin production| |production of molecular mediator of immune response| |leukocyte migration| |cell migration| |localization of cell| |cell motility| |locomotion| |movement of cell or subcellular component| |extracellular space| |immune response| |extracellular region| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp456|Benzoate 20000μM R08 exp456]]|-2.02| |[[:results:exp22|MLN-4924 2μM R00 exp22]]|-2| |[[:results:exp259|6-Thio-2-deoxyguanosine 2μM R06 exp259]]|-1.97| |[[:results:exp42|BI-6727 0.001μM R01 exp42]]|-1.7| |[[:results:exp530|Thioridazine 5μM R08 exp530]]|1.78| |[[:results:exp347|Cyclosporin-A 0.8μM R07 exp347]]|2.29| No correlation found to any other genes in chemogenomics.
