The specificity determinants surrounding the tyrosine phospho-acceptor sites have been determined by various procedures. In PTK assays using various substrates, it was determined that glutamic residues of the N-terminal or C-terminal side of the acceptor are often preferred. The substrate specificity of PTK catalytic domains has been analyzed by peptide library screening for prediction of the optimal peptide substrates. Finally, bioinformatics has been applied to identify phospho-acceptor sites in proteins of PTKs by application of a neural network algorithm. [Pg.132]

The regulation of mast-cell activity by biologically active peptides is an area of research, the rapid growth of which has been sparked in part by this intense interest in the interactions between neural, endocrine and immune systems [4, 26, 41] and in part by the recognition that activation of mast-cell secretion as a purely allergic IgE-dependent event is undoubtedly too restrictive. The involvement of the mast cell in the inflammatory response, for example, has for years been suspected to involve a number of non-immunologic, IgE-inde-pendent factors [24,42], Direct evidence for peptide involvement, however, has... [Pg.145]

In order to influence mast-cell function, peptides must be made available at sites very near to tissue mast cells. One means of accomplishing this is by specific peptidergic innervation. This would not necessarily require a classical synaptic morphology, but only the termination of nerves within the vicinity of mast cells [1,3]. Modulation of mast-cell secretion by peptides of neural origin is particularly attractive, for it would allow for a restricted, localized expression of peptide action in specific target tissues because of the selective distribution of each peptide within particular neurones. Moreover, this could be further modified and restricted by differing mast cell specificities. (Heterogeneity of mast cell responsiveness to peptide stimulation has been well documented [52, 53 ].) The result would permit a well-localized tissue response without systemic manifestation [3]. [Pg.147]

Hemopexin was first identified as a heme binding P-globin in elec-trophoretograms of plasma of patients with hemolysis (17-19). The protein is synthesized and secreted by the liver (20-22), and during secretion the signal peptide is removed and the protein is glycosylated (23). Tissue forms of hemopexin are expected due to the presence of mRNA in brain (24), peripheral neurons (25), and neural retina (26), pointing to a function of hemopexin in barrier tissues. [Pg.207]

The innervation of the gastrointestinal tract is complex. The myenteric and submucosal plexuses contain many interneurons. These possess a number of neurotransmitters and neuromodulators, including several peptides, such as enkephalins, substance P, and vasoactive intestinal peptide. Reflex activity within the plexuses regulates peristalsis and secretion locally. The effects of sympathetic and parasympathetic nerve stimulation are superimposed on this local neural regulation. [Pg.87]
