General annotation (Comments)

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. Ref.1 Ref.8
Catalytic activity	ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
Subunit structure	Forms a complex with Hsp83 and piwi; probably Hop mediates the interaction between piwi and Hsp83.
Subcellular location	Endomembrane system; Peripheral membrane protein By similarity. Note: Wholly intracellular, possibly membrane associated By similarity.
Developmental stage	Expressed both maternally and zygotically throughout development. Ref.1
Domain	Possesses two phosphotransferase domains. The second one probably contains the catalytic domain By similarity, while the presence of slight differences suggest a different role for domain 1 By similarity.
Sequence similarities	Belongs to the protein kinase superfamily. Tyr protein kinase family. JAK subfamily. Contains 1 FERM domain. Contains 2 protein kinase domains. Contains 1 SH2 domain.
Sequence caution	The sequence AAL48491.1 differs from that shown. Reason: Erroneous initiation.
