Genes affected

MYSM1 (HGNC:29401): (Myb like, SWIRM and MPN domains 1) Enables histone binding activity; peptidase activity; and transcription coactivator activity. Involved in several processes, including chromatin remodeling; monoubiquitinated histone H2A deubiquitination; and positive regulation of transcription by RNA polymerase II. Located in nucleolus and nucleoplasm. Part of protein-containing complex. Implicated in diabetic retinopathy. [provided by Alliance of Genome Resources, Apr 2022]
