motifs/domains
  • three WWE domains separated by glutamine-rich sequences at the N-terminus
  • domain 1 binding to NOTCH
  • domain 2, intermediate, containing a putative SH3 binding domain
  • C terminal domain 3 containing a RING-H2 zinc finger motif
  • HOMOLOGY
    interspecies homolog to Drosophila Deltex 1

    basic FUNCTION
  • cytosolic effector of Notch signaling thought to bind through its N-terminal domain to the Notch receptor
  • may playing a role in marginal zone B (MZB) cell differentiation
  • function as E3 ligases based on its capacity for self-ubiquitination (Takeyama 2003)
  • can act as a negative regulator of Notch signals in T cells but that endogenous levels of DTX1 and DTX2 are not important for regulating Notch signals during thymocyte development
  • CELLULAR PROCESS nucleotide, transcription

    REGULATION
    activated by in T-cell progenitors can block Notch signals, suggesting that Deltex1 may play an important role in regulating Notch signals during T-cell development
