This protein family is named Putative GRINL1B complex locus protein 2. GRINL1B is short for: glutamate receptor, ionotropic, N-methyl D-aspartate-like 1B. The name indicates what sort of receptor it is thought to be, a ligand gated ion channel specific to the neurotransmitter Glutamate. This family of proteins is found in eukaryotes. Proteins in this family are typically between 325 and 463 amino acids in length. The protein is thought to be the product of a pseudogene with a role in helping assemble a gene transcription unit.
