The RBM (RNA-binding motif) gene family encodes proteins with an RNA binding motif. RBM45, also known as developmentally-regulated RNA-binding protein 1 (DRB1), is a 476 amino acid protein that may play an important role in neural development. Structurally, RBM45 has four RNA recognition motifs (RRMs), however, due to a sequence divergence, it has been suggested that only three of the RRMs functionally bind RNA. These structural motifs are similar to those found in other neural RNA-binding proteins, such as Msi1, Hel-N1 and HuC, but RBM45 differs from these functionally similar proteins because it has a poly(C) RNA-binding preference. RBM45 is predominantly localized to the cytoplasm, but has also been shown to shuttle to the nucleus. Supporting its suggested role in neuronal development, RBM45 expression is highest in neuronal pregenitor cells, but is reduced in differentiated neural cells. There are three isoforms of RBM45 as a result of alternative splicing.
