General scheme of kinase function. A protein kinase is a kinase which selectively ... Up to 30% of all human proteins may be modified by kinase ... (also called c-kit ...
Mutations in kinases that lead to a loss-of-function or gain-of-function can cause cancer [8] and disease in humans, including certain types of leukemia and neuroblastomas, glioblastoma, [9] spinocerebellar ataxia (type 14), forms of agammaglobulinaemia, and many others. [10]
Checkpoint kinase 1, commonly referred to as Chk1, is a serine/threonine-specific protein kinase that, in humans, is encoded by the CHEK1 gene. [ 5 ] [ 6 ] Chk1 coordinates the DNA damage response (DDR) and cell cycle checkpoint response. [ 7 ]
The protein kinase domain is a structurally conserved protein domain containing the catalytic function of protein kinases. [2] [3] [4] Protein kinases are a group of enzymes that move a phosphate group onto proteins, in a process called phosphorylation. This functions as an on/off switch for many cellular processes, including metabolism ...
Creatine kinase in the blood may be high in health and disease. Exercise increases the outflow of creatine kinase to the blood stream for up to a week, and this is the most common cause of high CK in blood. [16] Furthermore, high CK in the blood may be related to high intracellular CK such as in persons of African descent. [17]
Protein kinase RNA-activated also known as protein kinase R (PKR), interferon-induced, double-stranded RNA-activated protein kinase, or eukaryotic translation initiation factor 2-alpha kinase 2 (EIF2AK2) is an enzyme that in humans is encoded by the EIF2AK2 gene on chromosome 2. [5] [6] PKR is a serine/tyrosine kinase that is 551 amino acids ...
The WEE1 gene has two known homologues in humans, WEE1 (also known as WEE1A) and WEE2 (WEE1B). The corresponding proteins are Wee1-like protein kinase and Wee1-like protein kinase 2 which act on the human Cdk1 homologue Cdk1. The homologue to Wee1 in budding yeast Saccharomyces cerevisiae is called Swe1.
RAC(Rho family)-alpha serine/threonine-protein kinase is an enzyme that in humans is encoded by the AKT1 gene. This enzyme belongs to the AKT subfamily of serine/threonine kinases that contain SH2 (Src homology 2-like) protein domains. [5] It is commonly referred to as PKB, or by both names as "Akt/PKB".
