tif212

Gene
tif212
Protein
Probable eukaryotic translation initiation factor 2 subunit beta
Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843)
Length
321 amino acids
Function
eIF-2 functions in the early steps of protein synthesis by forming a ternary complex with GTP and initiator tRNA. This complex binds to a 40S ribosomal subunit, followed by mRNA binding to form a 43S preinitiation complex. Junction of the 60S ribosomal subunit to form the 80S initiation complex is preceded by hydrolysis of the GTP bound to eIF-2 and release of an eIF-2-GDP binary complex. In order for eIF-2 to recycle and catalyze another round of initiation, the GDP bound to eIF-2 must exchange with GTP by way of a reaction catalyzed by eIF-2B (By similarity).
Similarity
Belongs to the eIF-2-beta/eIF-5 family.
