Description
KDM4D (lysine demethylase 4D) is a gene encoding a histone demethylase that specifically demethylates histone H3 lysine 9 (H3K9me3) and H3 lysine 36 (H3K36me3), playing a key role in epigenetic regulation, chromatin remodeling, and transcriptional activation. It is involved in cell cycle progression, DNA damage response, and is implicated in various cancers.

Protein Summary
KDM4D is a JmjC-domain-containing histone demethylase that removes methyl groups from H3K9me3 and H3K36me3, thereby activating transcription. It is involved in androgen receptor signaling, cell proliferation, and is overexpressed in several cancers, making it a potential therapeutic target.
