Protein attributes

Sequence length	144 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

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.
Tissue specificity	Ubiquitous.
Sequence similarities	Belongs to the eIF-1A family. Contains 1 S1-like domain.
