Summary: Enables histone H3S10 kinase activity. Involved in several processes, including heterochromatin boundary formation; protein modification process; and telomere maintenance. Located in chromosome. Part of X chromosome located dosage compensation complex, transcription activating. Is expressed in adult brain cell body rind. Orthologous to several human genes including RPS6KA5 (ribosomal protein S6 kinase A5). [provided by Alliance of Genome Resources, Jan 2025]

Data show that JIL-1 kinase (JIL-1) not only prevents heterochromatin formation but also coordinates chromatin-based regulation in the transcribed part of the genome.
Title: JASPer controls interphase histone H3S10 phosphorylation by chromosomal kinase JIL-1 in Drosophila.
our data indicate that the conserved H3S28 residue in metazoans has a role in supporting PRC2 catalysis.
Title: Histone H3 Serine 28 Is Essential for Efficient Polycomb-Mediated Gene Repression in Drosophila.
results strongly suggest that the action of JIL-1 depends on which telomere domain, which chromosome and which promoter is embedded in the telomere chromatin.
Title: The JIL-1 kinase affects telomere expression in the different telomere domains of Drosophila.
JIL-1 regulated heterochromatin in the context of the chromocenter and fourth chromosome by creating a composite H3S10phK9me2 mark together with the Su(var)3-9 methyltransferase.
Title: Histone H3S10 phosphorylation by the JIL-1 kinase in pericentric heterochromatin and on the fourth chromosome creates a composite H3S10phK9me2 epigenetic mark.
Enrichment of JIL-1 and the H3S10ph mark are predominantly associated with active genes in Drosophila.
Title: Genome-wide analysis of regulation of gene expression and H3K9me2 distribution by JIL-1 kinase mediated histone H3S10 phosphorylation in Drosophila.
The results suggest that JIL-1 is not a histone H3S28 kinase and that it is not involved in 14-3-3 recruitment in Drosophila.
Title: Evidence against a role for the JIL-1 kinase in H3S28 phosphorylation and 14-3-3 recruitment to active genes in Drosophila.
epigenetic H3S10 phosphorylation mark itself functions as a causative regulator of chromatin structure independently of any structural contributions from the JIL-1 protein.
