sec63 | Translocation protein sec63; Acts as component of the Sec62/63 complex which is involved in SRP-independent post-translational translocation across the endoplasmic reticulum (ER) and functions together with the Sec61 complex and bip1 in a channel-forming translocon complex. A cycle of assembly and disassembly of Sec62/63 complex from sec61 may govern the activity of the translocon. sec63 may affect sec61-polypeptide interactions by increasing the affinity of targeting pathways for sec61 and/or by modifying sec61 to allow more efficient polypeptide interaction. May also be involved in S [...] (611 aa) | ||||
dom34 | Protein dom34; Involved in protein translation. Together with hbs1, may function in recognizing stalled ribosomes and triggering endonucleolytic cleavage of the mRNA, a mechanism to release non- functional ribosomes and degrade damaged mRNAs. The complex formed by dom34 and hbs1 has ribonuclease activity towards double-stranded RNA substrates, but does not cleave single-stranded RNA. Acts as endonuclease; has no exonuclease activity. Increases the affinity of hbs1 for GTP, but nor for GDP. Promotes G1 progression and differentiation and is involved in mitotic and meiotic cell divisions [...] (390 aa) | ||||
hbs1 | Elongation factor 1 alpha-like protein; Involved in protein translation. Together with dom34, may function in recognizing stalled ribosomes and triggering endonucleolytic cleavage of the mRNA, a mechanism to release non- functional ribosomes and degrade damaged mRNAs (By similarity).
