Supplementary information

The EZHIP (EZH Inhibitory Protein) also known as CATACOMB is a protein that inhibits the activity of EZH2 an important enzyme in the PRC2 (Polycomb Repressive Complex 2). EZHIP is a protein with a molecular mass of approximately 90 kDa. It expresses in various tissues with notable presence in the male and female reproductive tracts as well as in several cancer cell lines. The protein's role involves modulating chromatin structure by interfering with methyltransferase activity affecting gene silencing.
Biological function summary

EZHIP interacts with the Polycomb Repressive Complex 2 (PRC2) altering its methylation activity on histone H3 at lysine 27 (H3K27me3) an important mark for epigenetic gene silencing. By engaging the complex EZHIP hinders the catalytic efficiency of EZH2 reducing the repression of target genes. This interaction significantly impacts epigenetic regulation as alterations to methylation patterns influence cellular functions and differentiation processes.

Pathways

EZHIP's function affects pathways related to chromatin modification and epigenetic regulation. It is central to the regulation of the JAK-STAT signaling pathway and interacts closely with EZH2 and possibly other members of the Polycomb group proteins. EZHIP shapes the chromatin landscape influencing the transcriptional output by collaborating or competing with other transcription factors and modifiers within these pathways.

EZHIP's aberrant expression is linked to cancers including gliomas and germ cell tumors. The relationship between EZHIP and EZH2 becomes important as alterations in EZH2 activity lead to abnormal gene silencing associated with oncogenesis. Additionally research indicates that dysregulation involving EZHIP might contribute to developmental disorders through improper epigenetic marks. Further study about its interactions could provide insights into therapeutic approaches for conditions linked to epigenetic misregulation.

Target data

Inhibits PRC2/EED-EZH1 and PRC2/EED-EZH2 complex function by inhibiting EZH1/EZH2 methyltransferase activity, thereby causing down-regulation of histone H3 trimethylation on 'Lys-27' (H3K27me3) (PubMed : 29909548, PubMed : 30923826, PubMed : 31086175, PubMed : 31451685). Probably inhibits methyltransferase activity by limiting the stimulatory effect of cofactors such as AEBP2 and JARID2 (PubMed : 30923826). Inhibits H3K27me3 deposition during spermatogenesis and oogenesis (By similarity).
