Genes affected

PPM1M (HGNC:26506): (protein phosphatase, Mg2+/Mn2+ dependent 1M) Predicted to enable manganese ion binding activity and phosphoprotein phosphatase activity. Predicted to be involved in protein dephosphorylation. Predicted to be located in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TWF2 (HGNC:9621): (twinfilin actin binding protein 2) The protein encoded by this gene was identified by its interaction with the catalytic domain of protein kinase C-zeta. The encoded protein contains an actin-binding site and an ATP-binding site. It is most closely related to twinfilin (PTK9), a conserved actin monomer-binding protein. [provided by RefSeq, Jul 2008]
