Selected 14-3-3ζ-associated proteins identified by TAP-MS from transgenic mouse brains

Proteins were identified through a search of LC-MS/MS data against a combined human and mouse protein database, and the corresponding human proteins are listed according to their unique Human Genome Organisation (HUGO) gene symbols and National Center for Biotechnology Information (NCBI) gene ID. Domain composition obtained from SMART (Simple Modular Architecture Research Tool; and Pfam (Protein Family Database; is indicated. The absence (0) or the number (1–6) of consensus binding sites (CS) for 14-3-3 proteins are shown. UBA, ubiquitin-associated; RIIa, RIIα, regulatory subunit portion of type II PKA R-subunit; cNMP, cyclic nucleotide monophosphate-binding domain; ADK, adenylate kinase; RBD, ras-binding domain; C1, protein kinase C conserved region 1; STYKc, tyrosine kinase-like domain; PI4Kc, phosphoinositide 4-kinase, catalytic domain; IPK, inositol polyphosphate kinase; SAM, sterile α motif; DENN, differentially expressed in neoplastic versus normal cells; PH, pleckstrin homology domain; SH3, Src homology domain 3; RA, Ras association domain; RasGEF_N, GEF for Ras-like GTPases, N-terminal domain; RasGRF, Ras protein-specific guanine nucleotide-releasing factor domain; C2, protein kinase C conserved region 2; SEC14, Sec14p-like lipid-binding domain; ANK, ankyrin repeats; ArfGap, putative GTPase-activating proteins for the small GTPase ARF; IQ, calmodulin-binding motif; RasGEFN, GEF for Ras-like GTPases, N-terminal motif; VHP, Villin headpiece domain; CAP-Gly, cytoskeleton-associated proteins-Gly domain; KISc, kinesin motor domain; TPR, tetratricopeptide repeat domain; WH1, WASp homology domain 1; Iso_dh, isocitrate/isopropylmalate dehydrogenase; RING, Really Interesting New Gene domain; MIR, domain in ryanodine and inositol trisphosphate receptors and protein O-mannosyltransferases; RYDR_ITPR, RIH (RyR and IP3R homology) domain; BTB_POZ, BTB (for BR-C, ttk, and bab)/POZ (for pox virus and zinc finger) domain; K_tetra, K+ channel tetramerization domain; Aldo_ket_red, aldo/keto reductase family; BRLZ, basic region leucin zipper.
