CIRH1A blocking peptide
CIRH1A Antibody (N-term) Blocking Peptide
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a WD40-repeat-containing protein that is localized to the nucleolus. Mutation of this gene causes North American Indian childhood cirrhosis, a severe intrahepatic cholestasis that results in transient neonatal jaundice, and progresses to periportal fibrosis and cirrhosis in childhood and adolescence. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jan 2016]
Uniprot Description
CIRH1A: May be a transcriptional regulator. Acts as a positive regulator of HIVEP1 which specifically binds to the DNA sequence 5'-GGGACTTTCC-3' found in enhancer elements of numerous viral promoters such as those of HIV-1, SV40, or CMV. Defects in CIRH1A are the cause of North American Indian childhood cirrhosis (NAIC). NAIC is a severe autosomal recessive intrahepatic cholestasis, originally described in Ojibway-Cree children from northwestern Quebec. NAIC typically presents with transient neonatal jaundice, in a child who is otherwise healthy, and progresses to biliary cirrhosis and portal hypertension. Biochemical and histopathological features suggest involvement of the bile ducts rather than of the bile canaliculi. They include elevated gamma glutamyltransferase and alkaline phosphatase levels, and, typically, marked fibrosis around bile ducts. Clinically, NAIC is distinct from other nonsyndromic familial cholestases because of its marked cholangiopathic features and severe degree of fibrosis on liver histology. 3 isoforms of the human protein are produced by alternative splicing.

Product Notes
The CIRH1A utp4 (Catalog #AAA9228501) is a Blocking Peptide and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "CIRH1A, 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
