The CRAL-TRIO domain is found in GTPase-activating proteins (GAPs), guanine nucleotide exchange factors (GEFs) and a family of hydrophobic ligand binding proteins, including the yeast SEC14 protein and mammalian retinaldehyde- and alpha-tocopherol-binding proteins. (embl.de)
A common heterophilic ligand for these RTK family members is definitely Gas6 a vitamin K-dependent protein that is widely secreted by most cells including the lungs intestine Serping1 and vascular endothelium (43). (exposed-skin-care.net)
use an assay in which alkaline phosphatase-tagged cell surface proteins are used to stain live embryos overexpressing other cell surface proteins to identify Sticks and stones (Sns) as a possible ligand for the Lar receptor protein tyrosine phosphatase. (sciety.org)

Treatment of cells with interleukin-1 (IL-1) caused activation of the JNK isoforms. (umassmed.edu)
Comparison of the binding activity of the JNK isoforms demonstrated that the JNK proteins differ in their interaction with ATF2, Elk-1 and Jun transcription factors. (umassmed.edu)
Although mass spectrometry can measure most protein isoforms, the analytical level of sensitivity is insufficient for detection of important signalling proteins with single-cell resolution26. (irjs.info)

Desensitization of p21(ras) after stimulation of cells by growth factors and phorbol 12-myristate 13-acetate (PMA) correlates with hyperphosphorylation of the guanine nucleotide exchange factor Son-of-sevenless (Sos) and its dissociation from the adaptor protein Grb2 (Cherniack, A., Klarlund, J. K., Conway, B. R., and Czech, M. P. (1995) J. Biol. (umassmed.edu)
Nuclear importation of proteins is really a two-step procedure relating to the dimeric importin-α/β where the α-subunit straight binds the NLS theme and acts as an adaptor for importin-β. (molecularcircuit.com)

However, questions on how zinc transporters are regulated and effectively facilitate zinc flux contributing to cell signaling are largely unknown. (hindawi.com)
Given the low plasma concentration of zinc and its importance in cellular signaling, it is essential that the availability and distribution of "free" zinc (free zinc is used to differentiate zinc involved in cell signaling from zinc that tightly bound to protein and therefore thermodynamically unavailable) are tightly controlled [ 6 ].

The tumor suppressor phosphatase and tensin homolog (PTEN) is a pleiotropic enzyme, inhibiting phosphatidyl-inositol-3 kinase (PI3K) signaling in the cytosol and stabilizing the genome in the nucleus. (biomedcentral.com)
Spry1, Spry2, and Spry4 but not Spry3 are induced transcriptionally and limit the duration and intensity mainly of ERK phosphorylation in response to growth factor (GF) stimulation (with the exception of EGF signaling). (springer.com)
Pure T-cell deficiencies are caused by defects in either a CD3 subunit (such as CD3 δ, CD3 ζ, CD3 ε ) or in CD45 tyrosine phosphatase, key proteins involved in pre-TCR and/or TCR signaling at the positive selection stage. (medscape.com)
