A number of ELISA Kits are available that target Citron, an alias of the protein, citron rho-interacting serine/threonine kinase. The human protein, encoded by the gene CIT, is an enzyme and member of the Protein kinase superfamily, AGC Ser/Thr protein kinase family. The protein's cellular localization is indicated to be cytoplasmic. Additional synonyms or past names for this protein may include: CITK, CRIK, MCPH17, STK21. Homology is conserved in other species, such as Mouse, Rat, Frog.
