Papers on SNAP50
Genomic analysis of sequence-dependent DNA curvature in Leishmania.
Garat et al., Montevideo, Uruguay. In Plos One, 2012
Those include divergent strand-switch regions between directional gene clusters and regions linked to markers of active transcription initiation such as acetylated H3 histone, TRF4 and SNAP50.
Histone acetylations mark origins of polycistronic transcription in Leishmania major.
Myler et al., Seattle, United States. In Bmc Genomics, 2008
RESULTS: The chromosomal location of TATA-binding protein (TBP or TRF4), Small Nuclear Activating Protein complex (SNAP50), and H3 histones were assessed in Leishmania major using microarrays hybridized with DNA obtained through chromatin immunoprecipitation (ChIP-chip).

SNAP50 zinc finger domain contributes to cooperative promoter recognition by human SNAPC
Co-expression of multiple subunits enables recombinant SNAPC assembly and function for transcription by human RNA polymerases II and III.
Henry et al., East Lansing, United States. In Protein Expr Purif, 2006
SNAP(C) consists of five subunits: SNAP190, SNAP50, SNAP45, SNAP43, and SNAP19.
Involvement of SRD2-mediated activation of snRNA transcription in the control of cell proliferation competence in Arabidopsis.
Sugiyama et al., Tokyo, Japan. In Plant J, 2005
The SRD2 gene encodes a nuclear protein that shares sequence similarity with the human SNAP50 protein, which is a subunit of SNAPc and is required for snRNA transcription in vitro.
Failure to detect binding of Trypanosoma brucei SNAPc to U2 and U6 snRNA gene sequences by in vitro transcription competition and pull-down assays.
Günzl et al., Farmington, United States. In Mol Biochem Parasitol, 2004
Previously, we have characterized and epitope-tagged the Trypanosoma brucei homologue of the SNAP50 subunit.
The Trypanosoma brucei spliced leader RNA and rRNA gene promoters have interchangeable TbSNAP50-binding elements.
Günzl et al., Farmington, United States. In Nucleic Acids Res, 2003
Since p57 and its T.brucei counterpart are homologous to SNAP50, a component of the human small nuclear RNA gene activation protein complex (SNAPc), both SLRNA and RRNA transcription in T.brucei may depend on a SNAPc-like transcription factor.
The small nuclear RNA-activating protein 190 Myb DNA binding domain stimulates TATA box-binding protein-TATA box recognition.
Henry et al., East Lansing, United States. In J Biol Chem, 2003
To investigate the role of SNAP(c) for TBP function at U6 promoters, TBP recruitment assays were performed using full-length TBP and a mini-SNAP(c) containing SNAP43, SNAP50, and a truncated SNAP190.
Redundant cooperative interactions for assembly of a human U6 transcription initiation complex.
Hernandez et al., New York City, United States. In Mol Cell Biol, 2002
The PSE is recognized by the snRNA-activating protein complex (SNAP(c)), which consists of five types of subunits, SNAP190, SNAP50, SNAP45, SNAP43, and SNAP19.
A map of protein-protein contacts within the small nuclear RNA-activating protein complex SNAPc.
Hernandez et al., United States. In J Biol Chem, 2001
This factor, the snRNA-activating protein complex or SNAP(c), binds to the PSE of both types of promoters and contains five types of subunits, SNAP190, SNAP50, SNAP45, SNAP43, and SNAP19.

Henry et al., East Lansing, United States. In Mol Cell Biol, 2000
RB also interacts with two SNAP(c) subunits, SNAP43 and SNAP50.
SNAP19 mediates the assembly of a functional core promoter complex (SNAPc) shared by RNA polymerases II and III.
Hernandez et al., New York City, United States. In Genes Dev, 1998
Here we reconstitute SNAPc from five recombinant subunits, SNAP43, SNAP45, SNAP50, SNAP190, and a newly identified subunit, SNAP19.
The large subunit of basal transcription factor SNAPc is a Myb domain protein that interacts with Oct-1.
Hernandez et al., New York City, United States. In Mol Cell Biol, 1998
SNAPc consists of at least four stably associated subunits, SNAP43, SNAP45, SNAP50, and SNAP190.
Cloning and characterization of SNAP50, a subunit of the snRNA-activating protein complex SNAPc.
Hernandez et al., United States. In Embo J, 1997
Here we report the isolation of cDNAs encoding the 50 kDa subunit of SNAPc, SNAP50.
