VPREB1 (V-set pre-B cell surrogate light chain 1)

Gene

• Entrez ID: 7441
• Gene name: V-set pre-B cell surrogate light chain 1
• Gene symbol: VPREB1
• Synonyms (NCBI Gene): CD179a, IGI, IGVPB, VPREB
• Chromosome: 22
• Chromosome location: 22q11.22
• 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 t
