May act at an RNAP assembly step prior to nuclear import (PubMed:21768307). Forms an interface between the RNA polymerase II enzyme and chaperone/scaffolding proteins, suggesting that it is required to connect RNA polymerase II to regulators of protein complex formation (PubMed:17643375). May be involved in nuclear localization of XPA (PubMed:11058119). {ECO:0000269|PubMed:17643375, ECO:0000269|PubMed:20855544, ECO:0000269|PubMed:21768307, ECO:0000305|PubMed:11058119}. |GTP EFTU| |ATP bind 1| |GTPase activity| |GTP binding| |mitochondrion| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp233|EPZ-5676 30μM R05 exp233]]|-2.37| |[[:results:exp473|Cincreasin 100μM R08 exp473]]|-2.15| |[[:results:exp160|Ribavirin 10 to 15μM on day4 R04 exp160]]|-2.05| |[[:results:exp216|Erlotinib 10μM R05 exp216]]|-1.83| |[[:results:exp147|Resveratrol 16μM R03 exp147]]|1.72| No correlation found to any other genes in chemogenomics.
