Function

[TERA_MOUSE] Necessary for the fragmentation of Golgi stacks during mitosis and for their reassembly after mitosis. Involved in the formation of the transitional endoplasmic reticulum (tER). The transfer of membranes from the endoplasmic reticulum to the Golgi apparatus occurs via 50-70 nm transition vesicles which derive from part-rough, part-smooth transitional elements of the endoplasmic reticulum (tER). Vesicle budding from the tER is an ATP-dependent process. The ternary complex containing UFD1L, VCP and NPLOC4 binds ubiquitinated proteins and is necessary for the export of misfolded proteins from the ER to the cytoplasm, where they are degraded by the proteasome. The NPLOC4-UFD1L-VCP complex regulates spindle disassembly at the end of mitosis and is necessary for the formation of a closed nuclear envelope. Regulates E3 ubiquitin-protein ligase activity of RNF19A (By similarity). Component of the VCP/p97-AMFR/gp78 complex that participates in the final step of the sterol-mediated ubiquitination and endoplasmic reticulum-associated degradation (ERAD) of HMGCR. Also involved in DNA damage response: recruited to double-strand breaks (DSBs) sites in a RNF8- and RNF168-dependent manner and promotes the recruitment of TP53BP1 at DNA damage sites. Recruited to stalled replication forks by SPRTN: may act by mediating extraction of DNA polymerase eta (POLH) to prevent excessive translesion DNA synthesis and limit the incidence of mutations induced by DNA damage (By similarity).

Publication Abstract from PubMed

The ATPases associated with various cellular activities (AAA) protein p97 has been implicated in a variety of cellular processes, including endoplasmic reticulum-associated degradation and homotypic membrane fusion. p97 belongs to a subgroup of AAA proteins that contains two nucleotide binding domains, D1 and D2. We determined the crystal structure of D2 at 3.0 A resolution. This model enabled rerefinement of full-length p97 in different nucleotide states against previously reported low-resolution diffraction data to significantly improved R values and Ramachandran statistics. Although the overall fold remained similar, there are significant improvements, especially around the D2 nucleotide binding site. The rerefinement illustrates the importance of knowledge of high-resolution structures of fragments covering most of the whole molecule. The structures suggest that nucleotide hydrolysis is transformed into larger conformational changes by pushing of one D2 domain by its neighbor in the hexamer, and transmission of nucleotide-state information through the D1-D2 linker to displace the N-terminal, effector binding domain.
