Rabbit Anti-GRC5/FITC Conjugated antibody
background:
PHF2 is a 1,101 amino acid protein belonging to the PHD finger protein family. Members of the PHD finger protein family function as transcriptional regulators that affect gene expression by modulating chromatin structure. Expressed in a wide variety of tissues, PHF2 localizes to the nucleus and contains one PHD-type zinc finger and one JMJC domain, suggesting a possible role for PHF2 in transcription regulation and chromatin remodeling. The gene encoding PHF2 lies in the candidate region for hereditary sensory neuropathy type I (HSN1), a disorder characterized by sensory dysfunction. PHF2 exhists as two isoforms produced by alternative splicing, designated isoform 1 and 2 respectively.
Function:
Lysine demethylase that demethylates both histones and non-histone proteins. Enzymatically inactive by itself, and becomes active following phosphorylation by PKA: forms a complex with ARID5B and mediates demethylation of methylated ARID5B. Demethylation of ARID5B leads to target the PHF2-ARID5B complex to target promoters, where PHF2 mediates demethylation of dimethylated 'Lys-9' of histone H3 (H3K9me2), followed by transcription activation of target genes. The PHF2-ARID5B complex acts as a coactivator of HNF4A in liver. PHF2 is recruited to trimethylated 'Lys-4' of histone H3 (H3K4me3) at rDNA promoters and promotes expression of rDNA.
Subunit:
Component of the PHF2-ARID5B complex, at least composedof PHF2 and ARID5B. Interacts with HNF4A and NR1H4.
Subcellular Location:
Nucleus, nucleolus.
Tissue Specificity:
Widely expressed, including in liver (at protein level).
Post-translational modifications:
Phosphorylated by PKA on specific serine residues, leading to the formation of an active lysine demethylase complex.
Similarity:
Belongs to the JHDM1 histone demethylase family. JHDM1D subfamily.
Contains 1 JmjC domain.
Contains 1 PHD-type zinc finger.
