Mphosph8 Gene Summary [Mouse]
Predicted to enable chromatin binding activity and methylated histone binding activity. Predicted to be involved in negative regulation of gene expression via chromosomal CpG island methylation; negative regulation of single stranded viral RNA replication via double stranded DNA intermediate; and transposable element silencing by heterochromatin formation. Predicted to be located in several cellular components, including cytosol; heterochromatin; and nuclear lumen. Predicted to be part of nucleosome. Predicted to be active in cytoplasm and nucleus. Is expressed in inner cell mass and trophectoderm. Orthologous to human MPHOSPH8 (M-phase phosphoprotein 8). [provided by Alliance of Genome Resources, Apr 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Mphosph8 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- Chromatin organization modifier domain
- histone binding
- transcription regulator
- Ankyrin repeats (many copies)
- CHROMO (CHRromatin Organization Modifier) domains and chromo shadow domains
- protein binding activity, bridging
- Ankyrin repeats (3 copies)
- chromatin binding
- protein binding
- Chromo (CHRromatin organization MOdifier) domain
- Ankyrin repeat
