Cryptocephal, isoform A; Cryptocephal (crc) encodes a protein that belongs to a member of the CREB/ATF family of basic-leucine zipper transcription factors. It serves as an coactivator of the product EcR of to promote expression the molting peptide hormone encoded by ETH. It also acts as an unfolded protein response transcription factor to regulate glycolytic genes in response to ER stress.

X box binding protein-1 (Xbp1) encodes a transcription factor that mediates the unfolded protein response. Xbp1 mRNA undergoes splicing after being cleaved by the product of Ire1, inducing the expression of ER quality control transcripts. Xbp1 mutants fail to develop beyond the 2nd instar larval stage, indicative of a requirement to resolve inherent ER stress during normal development.

Histone deacetylase HDAC1; Catalyzes the deacetylation of lysine residues on the N- terminal part of the core histones (H2A, H2B, H3 and H4). Histone deacetylation may constitute a tag for epigenetic repression and plays an important role in transcriptional regulation, cell cycle progression and developmental events. For instance, deacetylation of histone H3 may be a prerequisite for the subsequent recruitment of the histone methyltransferase Su(var)3-9 to histones. Involved in position-effect variegation (PEV). In the larval brain, part of a regulatory network including the transcript [...]

Maf-S, isoform B; DNA-binding transcription factor activity; sequence-specific DNA binding; protein heterodimerization activity; RNA polymerase II cis-regulatory region sequence-specific DNA binding. It is involved in the biological process described with: positive regulation of transcription by RNA polymerase II; head development.

P38a MAP kinase (p38a) encodes a member of the mitogen-activated protein kinases responsive to diverse stresses. In immune response, it activates its downstream component encoded by Atf-2 that in turn regulates Duox expression.

Transcription factor kayak, isoforms A/B/F; Developmentally regulated transcription factor AP-1 binds and recognizes the enhancer DNA sequence: 5'-TGA[CG]TCA-3'. May play a role in the function or determination of a particular subset of cells in the developing embryo. It is able to carry out its function either independently of or in conjunction with Jra. Belongs to the bZIP family. Fos subfamily.

Atf6, isoform C; DNA-binding transcription factor activity. It is involved in the biological process described with: regulation of transcription, DNA-templated.

Asparagine synthase (glutamine-hydrolyzing) activity. It is involved in the biological process described with: asparagine biosynthetic process.

Nuclear factor Y-box B (Nf-YB) encodes a subunit of the nuclear transcription factor Y, which binds to the CCAAT box regulatory sequence. It regulates gene transcription and is involved in eye and thorax development.
