Targeting adaptor protein SLP76 of RAGE as a therapeutic approach for lethal sepsis.
Title: Targeting adaptor protein SLP76 of RAGE as a therapeutic approach for lethal sepsis.
Biochemical analyses revealed that mutant T cells were hypersensitive to TCR stimulation. Indeed, phosphorylation of several signaling proteins, including SLP76 itself, phospholipase Cgamma1 and the protein kinases AKT and ERK1/2, was increased
Title: Serine Phosphorylation of SLP76 Is Dispensable for T Cell Development but Modulates Helper T Cell Function.
slp-76 contributes to the regulation of the tissue distribution, PLZF, and cytokine expression of iNKT cells via ADAP-dependent and -independent mechanisms.
Title: A mutation within the SH2 domain of slp-76 regulates the tissue distribution and cytokine production of iNKT cells in mice.
findings identify ACK1 as a novel SLP-76-associated protein-tyrosine kinase that modulates early activation events in T cells.
Title: Activated Cdc42-associated kinase 1 (ACK1) binds the sterile α motif (SAM) domain of the adaptor SLP-76 and phosphorylates proximal tyrosines.
immune cell adaptor SLP-76 binds directly to SUMO-RanGAP1 of cytoplasmic fibrils of the nuclear pore complex, and this interaction is needed for optimal NFATc1 and NF-kappaB p65 nuclear entry in T cells
Title: The Immune Adaptor SLP-76 Binds to SUMO-RANGAP1 at Nuclear Pore Complex Filaments to Regulate Nuclear Import of Transcription Factors in T Cells.
these studies establish Slp-76 as a critical determinant of NK-cell development and NK cell mediated elimination of missing-self target cells in mice
Title: Slp-76 is a critical determinant of NK-cell mediated recognition of missing-self targets.
Data show that a splice variant of SLP-76 signal transducing adaptor protein (SLP-76 or Lcp2) reduced the amount of SLP-76 protein by ~90%, disrupting immunogenic and tolerogenic pathways to different degrees.
Title: Quantitative reduction of the TCR adapter protein SLP-76 unbalances immunity and immune regulation.
this analysis identified 65 proteins not associated before with the Zap70-Lat-SLP-76 network and thus should provide cues for future functional experiments.
Title: Quantitative proteomics analysis of signalosome dynamics in primary T cells identifies the surface receptor CD6 as a Lat adaptor-independent TCR signaling hub.
A yopH mutant survived better in the absence of neutrophils, indicating that neutrophil inactivation by YopH by targeting PRAM-1/SKAP-HOM and SLP-76/Vav/PLCgamma2 signaling hubs may be critical for Yersinia survival.
Title: Identifying Yersinia YopH-targeted signal transduction pathways that impair neutrophil responses during in vivo murine infection.
analysis of a costimulatory mechanism by which CXCL12 and antigen converge at SLP-76 microcluster formation to enhance T cell responses
Title: The chemokine CXCL12 generates costimulatory signals in T cells to enhance phosphorylation and clustering of the adaptor protein SLP-76.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
