Gene Information

human ... CHEK1(1111)

General description

CHEK1 is a serine/threonine kinase that functions as a sensor for the stress response pathway in cells. It is activated by ATR kinase phosphorylation in response to DNA damage, and can subsequently modulate p53 phosphorylation. CHEK1 activity is inhibited by BCL6 in B cells.
Rabbit Anti-CHEK1 antibody recognizes zebrafish, bovine, chicken, human, mouse, rat, and canine CHEK1.

Immunogen

Synthetic peptide directed towards the middle region of human CHEK1

Application

Rabbit Anti-CHEK1 antibody can be used for western blot applications at a concentration of 0.5μg/ml. It can also be used for immunohistochemistry at 4-8μg/ml.

Biochem/physiol Actions

CHEK1 is required during normal S phase to avoid aberrantly increased initiation of DNA replication, thereby protecting against DNA breakage. Its expression is dispensable for somatic cell death and critical for sustaining G2 DNA damage checkpoint.

Sequence

Synthetic peptide located within the following region: WSCGIVLTAMLAGELPWDQPSDSCQEYSDWKEKKTYLNPWKKIDSAPLAL

Physical form

Purified antibody supplied in 1x PBS buffer with 0.09% (w/v) sodium azide and 2% sucrose.

Atr is a serine/threonine kinase, known to sense single-stranded DNA breaks and activate the DNA damage checkpoint by phosphorylating Chek1, which inhibits Cdc25, causing cell cycle arrest. This pathway has not been implicated in neuroregeneration. We show that in Drosophila

BCL6 is a transcriptional repressor protein that is expressed in a developmentally regulated fashion during B-cell maturation. Specifically, BCL6 is required for formation of germinal centers in response to T-cell dependent antigen activation. Germinal center B-cells feature the ability to

There are few reports describing the role of p53-dependent gene repression in apoptotic cell death. To identify such apoptosis-associated p53 target genes, we used the pro-oxidant plant-derived drug thymoquinone and compared p53+/+ and p53-/- colon cancer cells HCT116. The p53

Early-stage (I and II) ovarian carcinoma patients generally have good prognosis. Yet, some patients die earlier than expected. Thus, it is important to stratify early-stage patients into risk groups to identify those in need of more aggressive treatment regimens. The
