At4g11175

Gene
At4g11175
Protein
Translation initiation factor IF-1, chloroplastic
Organism
Arabidopsis thaliana
Length
141 amino acids
Function
One of the essential components for the initiation of protein synthesis. Stabilizes the binding of IF-2 and IF-3 on the 30S subunit to which N-formylmethionyl-tRNA(fMet) subsequently binds. Helps modulate mRNA selection, yielding the 30S pre-initiation complex (PIC). Upon addition of the 50S ribosomal subunit IF-1, IF-2 and IF-3 are released leaving the mature 70S translation initiation complex.
Similarity
Belongs to the IF-1 family.
