Recombinant Human Chromodomain-helicase-DNA-binding protein 1 (CHD1), Truncated

Uniprot Id

O14646

Target Species

Human

Target Name

CHD1

Target Full Name

Chromodomain-helicase-DNA-binding protein 1

Target Function

ATP-dependent chromatin-remodeling factor which functions as substrate recognition component of the transcription regulatory histone acetylation (HAT) complex SAGA. Regulates polymerase II transcription. Also required for efficient transcription by RNA polymerase I, and more specifically the polymerase I transcription termination step. Regulates negatively DNA replication. Not only involved in transcription-related chromatin-remodeling, but also required to maintain a specific chromatin configuration across the genome. Is also associated with histone deacetylase (HDAC) activity. Required for the bridging of SNF2, the FACT complex, the PAF complex as well as the U2 snRNP complex to H3K4me3. Functions to modulate the efficiency of pre-mRNA splicing in part through physical bridging of spliceosomal components to H3K4me3. Required for maintaining open chromatin and pluripotency in embryonic stem cells.

Target Subcellular Location

Nucleus. Cytoplasm.

Target Protein Families

SNF2/RAD54 helicase family

Target Tissue Specificity

Expressed in many tissues including in the brain, where the highest level of expression is found in the cerebellum and basal ganglia.

Target Background

The CHD family of proteins is characterized by the presence of chromo (chromatin organization modifier) domains and SNF2-related helicase/ATPase domains. CHD genes alter gene expression possibly by modification of chromatin structure thus altering access of the transcriptional apparatus to its chromosomal DNA template.
