Summary: Enables protein kinase activity. Involved in DNA integrity checkpoint signaling; microtubule cytoskeleton organization; and regulation of syncytial blastoderm mitotic cell cycle. Located in nucleus. Is expressed in adult brain; adult mushroom body; oocyte; organism; and primordial germ cell. Human ortholog(s) of this gene implicated in pancreatic cancer. Orthologous to human CHEK1 (checkpoint kinase 1). [provided by Alliance of Genome Resources, Dec 2024]

Title: Multiple Wnts act synergistically to induce Chk1/Grapes expression and mediate G2 arrest in Drosophila tracheoblasts.
The authors propose that ATR/Chk1 negatively regulate G2-M in developing tracheoblasts and that G2 arrest facilitates cellular and hypertrophic organ growth.

Grp was assumed to play a direct role in the immune response in D. melanogaster.

Relationships between DNA replication, chromosome condensation, and anaphase entry are mediated by the cell cycle kinases Grp (Chk1) and dWee1 (Wee1).

The Grp gene has been demonstrated to be a functional gene in the D. melanogaster genome, bit its function is yet to be determined.
Title: [Translational analysis of the Grp gene, a genomic homologue of the Gag gene of the gypsy retrotransposon of Drosophila melanogaster].
the Grp gene is not a pseudogene, but it is a functional gene of the D. melanogaster genome whose role remains to be elucidated.

A genetic screen identified grapes, the gene that encodes the Drosophila orthologue of checkpoint kinase 1 (CHK1). Knockdown of grapes by RNAi rescued eye development despite ongoing PERK activation.
Title: Impaired tissue growth is mediated by checkpoint kinase 1 (CHK1) in the integrated stress response.
The Grp gene product has a highly conserved structure in different species of the Drosophilidae family and is under stabilizing selection, which suggests its important genomic function in Drosophila.
