Identifier

IF1A

Protein name

RecName: Full=Translation initiation factor 1A; Short=aIF-1A;

Gene name

eif1a

FUNCTION: Seems to be required for maximal rate of protein biosynthesis. Enhances ribosome dissociation into subunits and stabilizes the binding of the initiator Met-tRNA(I) to 40 S ribosomal subunits (By similarity).

SIMILARITY: Belongs to the eIF-1A family.

SIMILARITY: Contains 1 S1-like domain.
