This product is monospecific antiserum processed by delipidation and defibrination followed by sterile filtration. This product reacts with human Cullin 1. Cross reactivity is expected against mouse Cul1 based on sequence homology.
纯化方法
Delipidation and defibrination.
免疫原
Synthetic peptide corresponding to amino acids 742-752 of Human Cul1 (C-terminus) coupled to KLH.
Western blot: This antibody reacts with human Cul1 (1/500-1/1,000, An 89.6 kDa bandcorresponding to human Cul1 is detected). Most cell lines expressing Cul1 can be used as apositive control. Immunoprecipitation: The antibody immunoprecipitates in vitro translated product andprotein from cell lysates (using HeLa or NIH-3T3). Do not IP in the presence of NP-40, butrather use 0.1 % SDS). ELISA (1/2,000-1/10,000). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.

Cullins assemble a potentially large number of ubiquitin ligases by binding to the RING protein ROC1 to catalyse polyubiquitination, as well as binding to various specificity factors to recruit substrates. Cullin 1 is an essential component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which mediates the ubiquitination of proteins involved in cell cycle progression, signal transduction and transcription. In the SCF complex, cul1 serves as a rigid scaffold that organizes the SKP1-F-box protein and RBX1 subunits. Cul1 may also contribute to catalysis through positioning of the substrate and the ubiquitin-conjugating enzyme. Cul1 is part of the SCF complex consisting of CUL1, RBX1, SKP1 and SKP2, where it interacts directly with SKP1, SKP2 and RBX1. Cul1 also interacts with RNF7 and is part of a complex with TIP120A/CAND1 and RBX1. The unneddylated form interacts with TIP120A/CAND1 and the interaction negatively regulates the association with SKP1 in the SCF complex.Synonyms: CUL-1, CUL1, Cullin-1
