Drosophila/Vertebrate Genes in Development:


Gap gene family


kruppel


Definition:

Function:

Gap gene Kruppel (Kr) encodes a zinc finger protein with four tandomly repeated zinc finger domains.

Protein:

Zinc finger protein with four tandomly repeated zinc finger domains.


Regulatory Regions:

Two cis-acting control elements, CD1 and CD2, control early expression. CD2 is located at -1000 to -3000 from start of transcription, and CD1 is at -3000 to -4000.
