Within the HIPK family, HIPK1 and HIPK2 are the most closely related members, sharing about 93% sequence identity in their kinase domains, while HIPK3 is slightly less conserved with 87% identity. (nature.com)

There are a number of conserved regions in the catalytic domain of protein kinases. (embl.de)

The ArfGAP paxillin kinase linker (PKL)/G protein-coupled receptor kinase-interacting protein (GIT)2 continues to be implicated in regulating cell spreading and motility through its transient recruitment of the p21-activated kinase (PAK) to focal adhesions. (healthyguide.info)

This mutation decreases the affinity of tyrosine kinase inhibitors while raising the leukemogenic signaling of BCR-Abl [7]C[9]. (phytid.org)

c-Src should not be confused with CSK (C-terminal Src kinase), an enzyme that phosphorylates c-Src at its C-terminus and provides negative regulation of Src's enzymatic activity. (wikipedia.org)
Little is known about how the kinase activity-deficient RYKs transduce Wnt signals. (biologists.com)
Derailed and SRC64B form a complex, which contains catalytically active SRC64B, the formation or stability of which requires SRC64B kinase activity. (biologists.com)
Flumatinib is an orally bioavailable tyrosine kinase inhibitor flumatinib, with potential antineoplastic activity. (targetmol.jp)

BX795 is an effective and selective PDK1 inhibitor (IC50: 6 nM), and its selectivity is 140- and 1600-fold for PDK1 over PKA and PKC in cell-free assays, respect. (targetmol.jp)

c-Src tyrosine kinase consists of the N-terminal unique region, the Src homology 3 (SH3), SH2, linker, kinase domain, and the regulatory C-terminal tail. (intechopen.com)
When Src is inactive, the phosphorylated tyrosine group at the 527 position interacts with the SH2 domain which helps the SH3 domain interact with the flexible linker domain and thereby keeps the inactive unit tightly bound. (wikipedia.org)

However, as opposed to what seen in the AKI model, IFN-treatment induced a moderate but significant reduction in HNF-1protein manifestation (Number 2C), whereas protein levels were drastically decreased (six- to seven-fold) when gene manifestation was inhibited with an siRNA, suggesting that these conditions did not fully recapitulate the condition where HNF-1protein large quantity is probably controlled by multiple cytokines.

Kinase enzymes that specifically phosphorylate tyrosine amino acids are termed tyrosine kinases. (wikipedia.org)

The DYRK family has been characterized in organisms from yeast to humans and can be divided into five subfamilies, class I DYRKs, class II DYRKs, YAKs, HIPKs, and PRP4s 1 . (nature.com)

Of the 90 unique tyrosine kinase genes identified in the human genome, 58 encode receptor tyrosine kinase proteins. (wikipedia.org)
For induction of endotoxic AKI, C57Bl6 mice received an intraperitoneal shot of LPS (10 mg/kg) that within 6 hours SCR7 inhibitor database induced AKI characterized by oliguria or anuria, BUN increase, and a dramatic upregulation of renal AKI biomarker genes, including and TNF-were observed early after the injection of LPS (Number 1A, Supplemental Number 1A). (bms-911543.com)
Concomitantly, a dramatic downregulation of the proximal tubule markers of the megalin-cubilin complex (and some of its target genes involved in mitochondrial biogenesis SCR7 inhibitor database and function (and target genes and and its target genes and was dramatically decreased after LPS injection.
