Protein attributes

Sequence length	1207 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Phosphorylates 'Ser-10' of histone H3. May regulate gene expression by establishing or maintaining the structure of more open chromatin regions. Also required for normal polytene chromosome structure, for oogenesis and for viability throughout development. Regulates the structure of polytene chromosomes in salivary glands. May phosphorylate 'Ser-1' of histone H2A. Ref.1 Ref.7 Ref.8 Ref.10 Ref.11
Catalytic activity	ATP + a protein = ADP + a phosphoprotein. Ref.1
Cofactor	Magnesium. Ref.1
Subunit structure	Interacts with lola. Interacts with proteins of the male specific lethal (MSL) dosage compensation complex; this interaction is mediated by the kinase domains. Ref.6 Ref.9
Subcellular location	Nucleus. Chromosome. Note: Associates with chromosomes throughout the cell cycle. Localizes to interband regions along the polytene chromosomes and is enriched almost two-fold on the male X chromosome compared to the autosome. Ref.1
Post-translational modification	Autophosphorylated in vitro. Ref.1 Ref.12
Sequence similarities	Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. Contains 1 AGC-kinase C-terminal domain. Contains 2 protein kinase domains.
Sequence caution	The sequence AAL28591.1 differs from that shown. Reason: Erroneous initiation.
