Recombinant Human PHD finger protein 21A (PHF21A)

Uniprot Id

Q96BD5

Target Species

Human

Target Name

PHF21A

Target Full Name

PHD finger protein 21A

Target Function

Component of the BHC complex, a corepressor complex that represses transcription of neuron-specific genes in non-neuronal cells. The BHC complex is recruited at RE1/NRSE sites by REST and acts by deacetylating and demethylating specific sites on histones, thereby acting as a chromatin modifier. In the BHC complex, it may act as a scaffold. Inhibits KDM1A-mediated demethylation of 'Lys-4' of histone H3 in vitro, suggesting a role in demethylation regulation.

Target Subcellular Location

Nucleus.

Target Tissue Specificity

Highly expressed in brain. Expressed at lower level in other tissues, including heart, kidney, liver, lung and skeletal muscle. Abundantly expressed in fetal brain.

Target Synonyms

BHC80a; BM-006; BRAF35-HDAC complex protein BHC80; BRAF35/HDAC2 complex (80 kDa); KIAA1696; PF21A_HUMAN; PHD finger protein 21A; PHF21A

Target Background

The PHF21A gene encodes BHC80, a component of a BRAF35 (MIM 605535)/histone deacetylase (HDAC; see MIM 601241) complex (BHC) that mediates repression of neuron-specific genes through the cis-regulatory element known as repressor element-1 (RE1) or neural restrictive silencer (NRS) (Hakimi et al., 2002 [PubMed 12032298]).
