CD307e, or Fc receptor-like 5, is a human gene encoded by FCRL5. It may also be known as: Fc receptor-like protein 5; FcR-like protein 5; FcRL5; BXMAS1; Fc receptor homolog 5; FcRH5; Immune receptor translocation-associated protein 2; CD antigen CD307e; CD307; IRTA2; PRO820. The encoded protein has an amino acid length of 977 and a mass of 106.4 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse.
