26S proteasome non-ATPase regulatory subunit 13 (PSMD13)
The protein contains 376 amino acids for an estimated molecular weight of 42945 Da.
Component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. This complex plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins, which could impair cellular functions, and by removing proteins whose functions are no longer required. Therefore, the proteasome participates in numerous cellular processes, including cell cycle progression, apoptosis, or DNA damage repair. (updated: Nov. 22, 2017)

CLONING
Ubiquitinated proteins are degraded by a 26S ATP-dependent protease. The protease is composed of a 20S catalytic proteasome and PA700, a 700-kD regulatory complex (see PSMC1; 602706). Hori et al. (1998) determined the partial protein sequences of bovine p28 (PSMD10; 603480) and p40.5, 2 components of PA700. By searching a sequence database, they identified cDNAs encoding the human p28 and p40.5 homologs. The predicted human p40.5 protein contains 376 amino acids and has a molecular mass of 43 kD. Using computerized homology searches, Hori et al. (1998) identified Nas7, an S. cerevisiae gene encoding a protein with 31% identity to p40.5. They disrupted the Nas7 gene and found that Nas7-deficient yeast cells were sensitive to heat stress. Northern blot analysis revealed that p40.5 was expressed as a 1.3-kb mRNA in all human tissues tested. By sequencing peptides obtained from purified 26S proteasome subunits, followed by database analysis and PCR of human myeloblast cell line RNA, Hoffman et al. (1999) cloned the PSMD13 gene, which they called subunit 11 (S11). The deduced 376-amino acid protein has a calculated molecular mass of 42.9 kD, and it shares 97% identity with mouse S11. Western blot analysis detected S11 at about 43 kD.GENE FUNCTION
By Far Western blot analysis, Hoffman et al. (1999) determined that S11 bound the 26S proteasome and the 19S regulatory complex, but not the 20S proteasome.MAPPING
The International Radiation Hybrid Mapping Consortium mapped the PSMD13 gene to chromosome 11 (TMAP STS-T99644). ... More on the omim web site
