Function

Regulator of post-transcriptional mitochondrial gene expression, required for assembly of the mitochondrial ribosome and for recruitment of mRNA and lncRNA. Binds RNAs containing the 14 base G-rich element. Preferentially binds RNAs transcribed from three contiguous genes on the light strand of mtDNA, the ND6 mRNA, and the long non-coding RNAs for MT-CYB and MT-ND5, each of which contains multiple consensus binding sequences (PubMed:23473033, PubMed:23473034, PubMed:29967381). Involved in the degradosome-mediated decay of non-coding mitochondrial transcripts (MT-ncRNA) and tRNA-like molecules (PubMed:29967381). Acts by unwinding G-quadruplex RNA structures in MT-ncRNA, thus facilitating their degradation by the degradosome (PubMed:29967381). G-quadruplexes (G4) are non-canonical 4 stranded structures formed by transcripts from the light strand of mtDNA (PubMed:29967381).

Activity summary

The G-rich RNA sequence binding factor 1 known as GRSF1 is a protein involved in RNA processing activities. Alternate names include MGC60760 and GAR1. This protein weighs approximately 48 kDa and demonstrates a wide expression pattern across different tissues with a marked presence in mitochondria. GRSF1 binds specifically to G-rich elements in RNA playing a mechanical role in stabilizing complex RNA structures and facilitating efficient RNA processing.

Biological function summary

The GRSF1 operates as an important player in mitochondrial RNA metabolism. It is known to interact within ribonucleoprotein complexes facilitating the regulation of mitochondrial gene expression. GRSF1 contributes to the maturation and processing of mitochondrial RNA impacting the proper synthesis of components essential for mitochondrial function. It ensures that mitochondrial encoded proteins are synthesized accurately aiding overall cellular energy production.

Pathways

GRSF1 engagement with organellar RNA processing integrates into mitochondrial biogenesis and maintenance pathways. This protein significantly influences the electron transport chain by ensuring the precise maturation of mitochondrial RNAs required for encoding electron transport chain components. It connects with proteins like LRPPRC as part of RNA granules coordinating gene expression regulation to support cellular respiration and energy conversion pathways.

Associated diseases and disorders

GRSF1 links closely to conditions involving mitochondrial dysfunctions such as mitochondrial myopathy. Alterations in GRSF1 function can result in impaired energy production leading to muscle weakness and other systemic symptoms associated with myopathy. It may also intersect with neurodegenerative disorders where mitochondrial impairment represents a common pathological feature. GRSF1's association with proteins like Twinkle helicase in such diseases emphasizes its broader implications in maintaining mitochondrial integrity and cellular health.
