Protein Structure

UniProt Annotation

Function

One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex.

Subcellular Localization

Mitochondrion.

Disease Associations

Tissue Specificity

Expressed in all tissues examined. Highest level in skeletal muscle.
