CC -!- FUNCTION: Prevents inappropriate targeting of non-secretory
CC polypeptides to the endoplasmic reticulum (ER). Binds to nascent
CC polypeptide chains as they emerge from the ribosome and blocks their
CC interaction with the signal recognition particle (SRP), which normally
CC targets nascent secretory peptides to the ER. Also reduces the inherent
CC affinity of ribosomes for protein translocation sites in the ER
CC membrane (M sites). May act as a specific coactivator for JUN, binding
CC to DNA and stabilizing the interaction of JUN homodimers with target
CC gene promoters. {ECO:0000269|PubMed:10982809,
CC ECO:0000269|PubMed:8047162, ECO:0000269|PubMed:9877153}.
CC -!- SUBUNIT: Part of the nascent polypeptide-associated complex (NAC),
CC which is a heterodimer of NACA and BTF3 (via NAC-A/B domains). NAC
CC associates with ribosomes through the BTF3/NACB subunit and contacts
CC the ribosomal protein L23, which is positioned near the exiting site.
CC Both subunits can contact nascent polypeptide chains. NACA may also
CC form homodimers, and only this form binds DNA. Interacts with TBP and
CC JUN (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC Note=The heterodimer is located mainly in the cytosol, and the
CC homodimer in the nucleus. {ECO:0000250}.
CC -!- DOMAIN: The positively charged inner surface of the NAC-A/B domain is
CC crucial for NACA localization in the nucleus and DNA-binding. This
CC region is blocked from binding nucleic acids in the heterodimeric
CC complex by a helix region in the beta-subunit, it also displays much
CC higher affinity for RNA than DNA (By similarity). {ECO:0000250}.
CC -!- PTM: Phosphorylation of Ser-43 by ILK during cell adhesion may promote
CC nuclear localization. Phosphorylation of Thr-159 by GSK3B may promote
CC proteasome mediated degradation.
CC -!- SIMILARITY: Belongs to the NAC-alpha family. {ECO:0000305}.
