CKA2/YOR061W Summary Help

Standard Name CKA2
Systematic Name YOR061W
Alias YOR29-12
Feature Type ORF, Verified
Description Alpha' catalytic subunit of casein kinase 2 (CK2); CK2 is a Ser/Thr protein kinase with roles in cell growth and proliferation; CK2, comprised of CKA1, CKA2, CKB1 and CKB2, has many substrates including transcription factors and all RNA polymerases; protein abundance increases in response to DNA replication stress; regulates Fkh1p-mediated donor preference during mating-type switching (1, 2, 3, 4, 5)
