Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 48 kDa (predicted molecular weight: 41 kDa).
IP 1/50.
  • Application notes
    Is unsuitable for Flow Cyt or ICC.
  • Target

    • Function
      Putative transcription factor involved in pancreas development and function.
    • Tissue specificity
      Expressed in lymphoid and pancreatic tissues.
    • Involvement in disease
      Defects in MNX1 are a cause of Currarino syndrome (CURRAS) [MIM:176450]. The triad of a presacral tumor, sacral agenesis and anorectal malformation constitutes the Currarino syndrome which is caused by dorsal-ventral patterning defects during embryonic development. The syndrome occurs in the majority of patients as an autosomal dominant trait.
