CHFR blocking peptide
CHFR Immunizing Peptide
NCBI and Uniprot Product Information
NCBI Description
This gene encodes an E3 ubiquitin-protein ligase required for the maintenance of the antephase checkpoint that regulates cell cycle entry into mitosis and, therefore, may play a key role in cell cycle progression and tumorigenesis. The encoded protein has an N-terminal forkhead-associated domain, a central RING-finger domain, and a cysteine-rich C-terminal region. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Mar 2014]
Uniprot Description
CHFR: E3 ubiquitin-protein ligase that functions in the antephase checkpoint by actively delaying passage into mitosis in response to microtubule poisons. Acts in early prophase before chromosome condensation, when the centrosome move apart from each other along the periphery of the nucleus. Probably involved in signaling the presence of mitotic stress caused by microtubule poisons by mediating the 'Lys-48'-linked ubiquitination of target proteins, leading to their degradation by the proteasome. Promotes the ubiquitination and subsequent degradation of AURKA and PLK1. Probably acts as a tumor suppressor, possibly by mediating the polyubiquitination of HDAC1, leading to its degradation. May also promote the formation of 'Lys-63'-linked polyubiquitin chains and functions with the specific ubiquitin-conjugating UBC13-MMS2 (UBE2N-UBE2V2) heterodimer. Substrates that are polyubiquitinated at 'Lys-63' are usually not targeted for degradation, but are rather involved in signaling cellular stress. Interacts with HDAC1 and HDAC2. Interacts with PML (with sumoylated form of PML). Ubiquitous. Belongs to the CHFR family. 5 isoforms of the human protein are produced by alternative splicing.

Product Notes
The CHFR chfr (Catalog #AAA425048) is a Blocking Peptide and is intended for research purposes only. The product is available for immediate purchase. The CHFR Immunizing Peptide reacts with Human, Mouse, Rat, Pig Cow and may cross-react with other species as described in the data sheet. The amino acid sequence is listed below: KFNHICEQTR FKN. It is sometimes possible for the material contained within the vial of "CHFR, Blocking Peptide" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
