| UniProt Protein Function: | VPREB1: 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. Belongs to the immunoglobulin superfamily. | 
| UniProt Protein Details: | Chromosomal Location of Human Ortholog: 22q11.22 Cellular Component: extracellular space Biological Process: immune response; immunoglobulin production | 
| NCBI Summary: | The protein encoded by this gene belongs to the immunoglobulin superfamily and is expressed selectively at the early stages of B cell development, namely, in proB and early preB cells. 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] |
