Interleukin 10 Receptor, beta, or Interleukin 10 receptor subunit beta, is a human gene encoded by IL10RB. It may also be known as: Interleukin-10 receptor subunit beta; IL-10 receptor subunit beta; IL-10R subunit beta; IL-10RB; Cytokine receptor class-II member 4; Cytokine receptor family 2 member 4; CRF2-4; Interleukin-10 receptor subunit 2; IL-10R subunit 2; IL-10R2; CD antigen CDw210b; CDW210B; CRFB4; D21S58; D21S66; interleukin 10 receptor, beta. The encoded protein has an amino acid length of 325 and a mass of 37.0 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Frog.
