Phylogenetic Profiles Reveal Structural and Functional Determinants of Lipid-binding.

Journal of proteomics & bioinformatics

Hong Y, Chalkia D, Ko KD, Bhardwaj G, Chang GS, van Rossum DB, Patterson RL.
PMID: 19946567
J Proteomics Bioinform. 2009 Mar 21;2:139-149. doi: 10.4172/jpb.1000071.

One of the major challenges in the genomic era is annotating structure/function to the vast quantities of sequence information now available. Indeed, most of the protein sequence database lacks comprehensive annotation, even when experimental evidence exists. Further, within structurally...

The incorporation of lysine analogs in Src Homology 2 (SH2) domain variants by Virdee et al. (2010) reveals the length-dependent contribution of a single amino acid side chain in recognition of phosphotyrosine-containing substrate peptides and a change in specificity...

Phosphotyrosine Kinase Assays as a Prescreen for Inhibitors of EGFr.

Methods in molecular medicine

Edwards J, Bartlett JM.
PMID: 21340815
Methods Mol Med. 2001;39:577-81. doi: 10.1385/1-59259-071-3:577.

The epidermal growth factor receptor (EGFr) is a 170-kDa glycosylated transmembrane protein found in a wide variety of tissues (1). It is the receptor for epidermal growth factor (EGF), transforming growth factor α (TGFα), and other related growth factor...

Tyrosine kinases in disease: overview of kinase inhibitors as therapeutic agents and current drugs in clinical trials.

Expert opinion on investigational drugs

Strawn LM, Shawver LK.
PMID: 15991993
Expert Opin Investig Drugs. 1998 Apr;7(4):553-73. doi: 10.1517/13543784.7.4.553.

Tyrosine kinases, first described as oncogenes, have been shown to play a role in normal cellular processes. Aberrations in tyrosine kinase activity lead to disease states. For fifteen years it has been postulated that the inhibition of tyrosine kinases...

Phosphotyrosine recognition domains: the typical, the atypical and the versatile.

Cell communication and signaling : CCS

Kaneko T, Joshi R, Feller SM, Li SS.
PMID: 23134684
Cell Commun Signal. 2012 Nov 07;10(1):32. doi: 10.1186/1478-811X-10-32.

SH2 domains are long known prominent players in the field of phosphotyrosine recognition within signaling protein networks. However, over the years they have been joined by an increasing number of other protein domain families that can, at least with...

STATs get their move on.

JAK-STAT

Reich NC.
PMID: 24470978
JAKSTAT. 2013 Oct 01;2(4):e27080. doi: 10.4161/jkst.27080. Epub 2013 Nov 13.

Understanding the mechanisms that regulate dynamic localization of a protein within a cell can provide critical insight to its functional molecular interactions. Signal transducers and activators of transcription (STATs) play essential roles in development, proliferation, and immune defense. However...

STAT3 expression is associated with poor survival in non-elderly adult patients with newly diagnosed multiple myeloma.

Blood research

Jung SH, Ahn SY, Choi HW, Shin MG, Lee SS, Yang DH, Ahn JS, Kim YK, Kim HJ, Lee JJ.
PMID: 29333406
Blood Res. 2017 Dec;52(4):293-299. doi: 10.5045/br.2017.52.4.293. Epub 2017 Dec 26.

BACKGROUND: Signal transducer and activator of transcription 3 (STAT3) is not only a key signaling molecule in the regulation of growth but is also involved in malignant transformation. We investigated the prognostic significance of STAT3 expression in 94 non-elderly...

Role of the N-terminal lid in regulating the interaction of phosphorylated MDMX with p53.

Oncotarget

Chan JV, Ping Koh DX, Liu Y, Joseph TL, Lane DP, Verma CS, Tan YS.

Murine double minute 4 protein (MDMX) is crucial for the regulation of the tumor suppressor protein p53. Phosphorylation of the N-terminal domain of MDMX is thought to affect its binding with the transactivation domain of p53, thus playing a...

Deregulation of tyrosine kinases in a rat macrophage tumor - ectopic expression of lck.
