Identifier

IF3

Protein name

RecName: Full=Translation initiation factor IF-3;

Identifier

IF3C

Protein name

RecName: Full=Translation initiation factor IF-3, chloroplastic;

Gene name

infC

FUNCTION: IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins (By similarity).

SUBUNIT: Monomer (By similarity).

SUBCELLULAR LOCATION: Cytoplasm (By similarity).

SUBCELLULAR LOCATION: Plastid, chloroplast.

SIMILARITY: Belongs to the IF-3 family.
