Genes affected

PKN2 (HGNC:9406): (protein kinase N2) Enables RNA polymerase binding activity; histone deacetylase binding activity; and protein serine/threonine kinase activity. Involved in several processes, including apical junction assembly; positive regulation of cell cycle; and positive regulation of viral genome replication. Located in several cellular components, including cleavage furrow; cytoskeleton; and midbody. [provided by Alliance of Genome Resources, Apr 2022]
