Putative RNA-binding protein 3 is a protein that in humans is encoded by the RBM3 gene.[4][5]

Function

This gene is a member of the glycine-rich RNA-binding protein family and encodes a protein with one RNA recognition motif (RRM) domain. Expression of this gene is induced by cold shock and low oxygen tension. A pseudogene exists on chromosome 1. Alternate transcriptional splice variants, encoding different isoforms, have been characterized.[5]

RBM3 is cold-induced RNA binding protein and is involved in mRNA biogenesis exerts anti-apoptotic effects.[6] According to antibody-based profiling and transcriptomics analysis, RBM3 protein is present in all analysed human tissues[7] and based on confocal microscopy mainly localised to the nucleoplasm.[8]

Clinical significance

RBM3 is a proto-oncogene that is associated with tumor progression and metastasis and is a potential cancer biomarker.[6] Based on patient survival data, high levels of RBM3 protein in tumor cells is a favourable prognostic biomarker in colorectal cancer.[9]
