No overt phenotype Normal paired pulse facilitation and post-tetanic potentiation Markedly reduced calcium fluxes and abrogated proliferation of thymocytes in response to TCR-CD3 cross-linking Reduced proliferation in thymoctes in response to Thy-1 cross-linking Largely normal proliferation of mature splenic T cells in response to TCR-CD3 cross-linking No reduction in proliferation induced by Thy-1 cross-linking in splenic T cells Blunted long-term potentiation Impaired spatial learning Increased number of granule cells in the dentate gyrus Increased number of pyramidal cells in the CA3 region Impaired suckling behavior Modified glomerular complex of the olfactory bulb Undulated hippocampal cell-layer
fyn, thymic isoform Normal maturation sequence in peripheral T cells in response to stimulation of the TCR with mitogen or antigen Lack of response of thymocytes to stimulation of the TCR with mitogen or antigen
Fyn Hypophosphorylation of nine proteins Reduced Focal adhesion kinase (FAK) activity FAK expressed in high levels in brain FAK not restricted to focal adhesion contacts FAK found in axons, dendrites, and intermediate filament cytoskeleton of astrocytes
Compensatory change in Src Family kinase activity found in brain extracts
Fyn-kinase-deficient mice were generated by replacing the SH2, SH3 and tyrosine kinase regions of fyn by lacZ. The targeting vector, pHFZpr-NeoDT, (G00-373-378) was ass....
In the fyn mutant mice the lacZ gene was inserted into exon 3 (fyn(z)) so that beta-galactosidase (beta-Gal) was expressed as a fusion protein with the Fyn unique region....
The LacZ gene was inserted into exon 3 in the in-frame so that it was expressed as the fusion protein with the Fyn-N-terminal region (a.a. 1-110); the region includes t....
