Small Ubiquitin-like Modifiers (SUMOs) are a family of small, related proteins that can be enzymatically attached to a target protein by a post-translational modification process termed sumoylation. Unlike ubiquitination, which targets proteins for degradation, sumoylation participates in a number of cellular processes, such as nuclear transport, transcriptional regulation, apoptosis, and protein stability. All SUMO proteins share the conserved ubiquitin domain and the C‑terminal diglycine cleavage/attachment site. Human SUMO3, also known as SMT3A, is synthesized as a 103 amino acid (aa), 11.5 kDa propeptide that contains an 11 aa C‑terminal prosegment. Following prosegment cleavage, the C‑terminal glycine is enzymatically attached to a lysine on a target protein. Human SUMO3 shares 83% sequence identity with SUMO3 from mouse. SUMO3 also has very high sequence homology to SUMO2 and SUMO4, 87% and 75%, respectively. SUMO3 shares only 47% sequence identity to SUMO1.

Scientific Data Images for Human/Mouse SUMO3 Antibody
Detection of Human SUMO3 by Western Blot.
Western blot shows lysates of A549 human lung carcinoma cell line, DU145 human prostate carcinoma cell line and mouse liver. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human/Mouse SUMO3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2959) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SUMO3 at approximately 11 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 4.
