Protein
Tyrosine-protein kinase hopscotch
Organism
Drosophila melanogaster
Function
Tyrosine kinase of the non-receptor type, phosphorylates the marelle protein. Required maternally for the establishment of the normal array of embryonic segments: involved in the control of pair-rule gene transcription in a stripe-specific manner. Together with Hsp83 and piwi, mediates canalization, also known as developmental robustness, likely via epigenetic silencing of existing genetic variants and suppression of transposon-induced new genetic variation.
Similarity
Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily.
