    at STAGE
  • two N terminal RNA binding motifs, RNP
  • RNA recognition motif, near the N-terminus, that may interact with binding partners (Yang 2009)
  • C-terminal proline-rich domain of DAZAP1 interacts with and neutralizes general splicing inhibitors, and is sufficient to activate splicing when recruited to pre-mRNA
    interspecies homolog to murine Dazap1
    CATEGORY RNA associated , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
  • predominantly in the nucleus and moves between the nucleus and the cytoplasm via a ZNS shuttling signal at its C-terminus
  • basic FUNCTION
  • involved in the spermatogenesis
  • playing a role, in cooperation with HNRNPA1 and HNRNPD, in processes such as mRNA transport and turnover (Yang 2009)
  • may cooperate with several HNRNPs to regulate ARE-containing mRNAs (Yang 2009)
  • stimulates translation initiation
  • ubiquitous hnRNP protein required for normal development and spermatogenesis
  • implicated in RNA transcription, splicing, and translation
  • RNA-binding protein involved in mammalian development and spermatogenesis, promoting inclusion of weak exons through specific recognition of diverse cis-elements
  • plays a pivotal role in the development of germ and somatic cells
  • CELLULAR PROCESS nucleotide, transcription
    PHYSIOLOGICAL PROCESS reproduction/sex
    a component
    small molecule
  • fusion MEF2D/DAZAP1 and/or DAZAP1/MEF2D contribute to leukemogenesis by altering signaling pathways normally regulated by wild-type MEF2D and DAZAP1
  • interaction with DAZ is disrupted by the phosphorylation of DAZAP1 at Thr269 and Thr315 in response to agonists that trigger the activation of ERK2 and the closely (Yang 2009) related ERK1
  • may interact with HNRPND, HNRPNA1, HNRNPAB and DDX20 via the C-terminus (Yang 2009)
  • SLIRP is a N42-binding protein which may regulate DAZAP1 subcellular localization
  • DAZAP1 regulates the splicing of CREM, CRISP2 and POT1 transcripts
  • is a negative regulator of pre-mRNA splicing and may control energy production in mitochondria by regulating COX6C expression
