Density-regulated protein homolog [Caenorhabditis elegans]

Protein Classification

SUI1 family translation initiation factor( domain architecture ID 10795723)

SUI1 family translation initiation factor is involved in the regulation of translation initiation, recognizing the start codon on mRNA by the ribosome and interacting with other components of the translation initiation complex to facilitate the assembly of the translation machinery.

Eukaryotic initiation factor 1 and related proteins; Members of the eIF1/SUI1 (eukaryotic initiation factor 1) family are found in eukaryotes, archaea, and some bacteria; eukaryotic members are understood to play an important role in accurate initiator codon recognition during translation initiation. eIF1 interacts with 18S rRNA in the 40S ribosomal subunit during eukaryotic translation initiation. Point mutations in the yeast eIF1 implicate the protein in maintaining accurate start-site selection but its mechanism of action is unknown. The function of non-eukaryotic family members is also unclear.

The function of non-eukaryotic family members is unclear. Escherichia coli YciH is a non-essential protein and was reported to be able to perform some of the functions of IF3 in prokaryotic initiation.
