Protein

Lethal(3)malignant brain tumor-like protein 3

Gene

L3mbtl3

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Putative Polycomb group (PcG) protein. PcG proteins maintain the transcriptionally repressive state of genes, probably via a modification of chromatin, rendering it heritably changed in its expressibility (By similarity). Required for normal maturation of myeloid progenitor cells.By similarity1 Publication
