Scientific Data Images for Human Ubiquitin Antibody

Detection of Human Ubiquitin antibody by Western Blot.

Detection of Human Ubiquitin by Western Blot.

Western blot shows lysates of HCT-116 human colorectal carcinoma cell line. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Ubiquitin Monoclonal Antibody (Catalog # A-104) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for Ubiquitin at approximately 5-10 & 37-250 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: Ubiquitin

Ubiquitin is a 76 amino acid (aa) protein that is ubiquitously expressed in all eukaryotic organisms. Ubiquitin is highly conserved with 96% aa sequence identity shared between human and yeast. In mammals, four ubiquitin genes encode for two ubiquitin­ribosomal fusion proteins and two polyubiquitin proteins. Cleavage of the ubiquitin precursors by deubiquitinating enzymes gives rise to identical ubiquitin monomers each with a predicted molecular weight of 8.6 kDa. Conjugation of ubiquitin to target proteins involves the formation of an isopeptide bond between the C­terminal glycine residue of ubiquitin and a lysine residue in the target protein. This process of conjugation, referred to as ubiquitination or ubiquitylation, is a multi­step process that requires three enzymes: a ubiquitin­activating (E1) enzyme, a ubiquitin­conjugating (E2) enzyme, and a ubiquitin ligase (E3). Ubiquitination is classically recognized as a mechanism to target proteins for degradation and as a result, ubiquitin was originally named ATP­dependent Proteolysis Factor 1 (APF­1). In addition to protein degradation, ubiquitination has been shown to mediate a variety of biological processes such as signal transduction, endocytosis, and post­endocytic sorting.
