Protocols
Specificity / Sensitivity
S5a/PSMD4 (D17E4) Rabbit mAb recognizes endogenous levels of total S5a/PSMD4 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human S5a/PSMD4 protein.
Western Blotting
Western blot analysis of extracts from various cell lines using S5a/PSMD4 (D17E4) Rabbit mAb.
Western Blotting
Western blot analysis of extracts from 293T cells, either mock transfected (-) or transfected with a Myc/DDK-tagged cDNA expression construct encoding full-length human S5a/PSMD4 (hS5a/PSMD4-Myc/DDK, +), using S5a/PSMD4 (D17E4) Rabbit mAb.
Background
S5a (PSMD4) is a subunit of the 19S regulatory proteasome complex functioning in ubiquitinated-protein targeting and degradation (1). S5a contains two polyubiquitin binding motifs (UIM) that bind multiubiquitin chains by hydrophobic interaction (2,3). In addition to ubiquitin, the UIM of S5a shows high affinity to a ubiquitin-like domain present in many proteins. S5a binds to these types of proteins directly and mediates their targeting to the proteasome for degradation (4,5).
