  2. Kinase - Wikipedia

    en.wikipedia.org/wiki/Kinase

    Dihydroxyacetone kinase in complex with a non-hydrolyzable ATP analog (AMP-PNP). Coordinates from PDB ID:1UN9. [1]In biochemistry, a kinase (/ ˈ k aɪ n eɪ s, ˈ k ɪ n eɪ s,-eɪ z /) [2] is an enzyme that catalyzes the transfer of phosphate groups from high-energy, phosphate-donating molecules to specific substrates.

  3. Protein kinase - Wikipedia

    en.wikipedia.org/wiki/Protein_kinase

    The human genome contains about 500 protein kinase genes and they constitute about 2% of all human genes. [1] There are two main types of protein kinase. The great majority are serine/threonine kinases, which phosphorylate the hydroxyl groups of serines and threonines in their targets.

  4. Protein kinase domain - Wikipedia

    en.wikipedia.org/wiki/Protein_kinase_domain

    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 ...

  5. CHEK1 - Wikipedia

    en.wikipedia.org/wiki/CHEK1

    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 ]

  6. Protein kinase R - Wikipedia

    en.wikipedia.org/wiki/Protein_kinase_R

    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 ...

  7. Tyrosine kinase - Wikipedia

    en.wikipedia.org/wiki/Tyrosine_kinase

    Protein tyrosine kinase plays a role in this task, too. A protein tyrosine kinase called pp125, also referred to as focal adhesion kinase (FAK) is likely at hand in the influence of cellular focal adhesions, as indicated by an immunofluorescent localization of FAK. Focal adhesions are macromolecular structures that function in the transmission ...

  8. Protein kinase C - Wikipedia

    en.wikipedia.org/wiki/Protein_kinase_C

    In cell biology, protein kinase C, commonly abbreviated to PKC (EC 2.7.11.13), is a family of protein kinase enzymes that are involved in controlling the function of other proteins through the phosphorylation of hydroxyl groups of serine and threonine amino acid residues on these proteins, or a member of this family.

  9. Creatine kinase - Wikipedia

    en.wikipedia.org/wiki/Creatine_kinase

    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]
