CD299, or C-type lectin domain family 4 member M, is a human gene encoded by CLEC4M. It may also be known as: CD209 antigen-like protein 1; DC-SIGN-related protein; DC-SIGNR; Dendritic cell-specific ICAM-3-grabbing non-integrin 2; DC-SIGN2; Liver/lymph node-specific ICAM-3-grabbing non-integrin; L-SIGN; CD antigen CD299; C-type lectin domain family 4, member M; CD209L; DCSIGNR; HP10347; LSIGN. The encoded protein has an amino acid length of 399 and a mass of 45.4 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Rat, Frog.
