RBM3 also known as RNA-binding motif protein 3 is a cold-inducible protein with a mass of approximately 17 kDa. It plays a role in binding RNA and is widely expressed in tissues including the brain heart and skeletal muscle. Research often highlights its involvement in temperature response implicating its role in cellular adaptation to cold stress. Overexpression of RBM3 has been documented during hypothermic conditions which suggests an adaptive function in extreme environments.

Biological function summary

RBM3 functions by modulating RNA stability and translation impacting cellular stress responses. It forms part of ribonucleoprotein complexes influencing the processing of several RNA species. The protein enhances mRNA stability under stress conditions and promotes cell survival by impacting protein synthesis. RBM3 also participates in synaptic plasticity which is essential for learning and memory showcasing its extensive influence on cellular functioning.

Pathways

RBM3 significantly contributes to neuroprotection and anti-apoptosis pathways. It is closely linked to pathways dealing with stress granules and mRNA stabilization. A known association exists between RBM3 and proteins such as CIRP (cold-inducible RNA-binding protein) which share similar pathways concerning mRNA regulation under cold conditions. This connection highlights RBM3's role in cell survival and stress management.

RBM3 has shown connections to neurodegenerative diseases and cancer. High levels of RBM3 expression correlate with improved outcomes in hypothermia-treated stroke and trauma patients due to its neuroprotective abilities. In cancer RBM3 links with proteins such as HIF-1α (hypoxia-inducible factor-1 alpha) where its overexpression has been associated with tumor progression in certain types suggesting RBM3's dual protective and pathological roles depending on the disease context.
