Anti-EIF3C Antibody Picoband®

Eukaryotic translation initiation factor 3 subunit C (eIF3c) is a protein that in humans is encoded by the EIF3C gene. Component of the eukaryotic translation initiation factor 3 (eIF-3) complex, which is required for several steps in the initiation of protein synthesis. The eIF-3 complex associates with the 40S ribosome and facilitates the recruitment of eIF-1, eIF-1A, eIF-2:GTP:methionyl-tRNAi and eIF-5 to form the 43S preinitiation complex (43S PIC) . The eIF-3 complex stimulates mRNA recruitment to the 43S PIC and scanning of the mRNA for AUG recognition. The eIF-3 complex is also required for disassembly and recycling of post-termination ribosomal complexes and subsequently prevents premature joining of the 40S and 60S ribosomal subunits prior to initiation.

Mediator of RNA polymerase II transcription subunit 4; Activator-recruited cofactor 36 kDa component; ARC36; Mediator complex subunit 4; TRAP/SMCC/PC2 subunit p36 subunit; Vitamin D3 receptor-interacting protein complex 36 kDa component; DRIP36; MED4; ARC36; DRIP36; VDRIP; HSPC126

Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.
