Mustard, isoform V; Mustard (mtd) encodes an ecdysone-regulated late puff protein. A isoform including only the C-terminal with a TLDc domain enters the nucleus. This isoform increases intestinal stem cell division and suppresses expression of the antimicrobial peptide encoded by DptA at the transcriptional level, independent of IMD pathway signaling.

Bb in a boxcar, isoform B; Diacylglycerol cholinephosphotransferase activity; ethanolaminephosphotransferase activity; phosphotransferase activity, for other substituted phosphate groups. It is involved in the biological process described with: phosphatidylethanolamine biosynthetic process; Belongs to the CDP-alcohol phosphatidyltransferase class-I family.

Serine/threonine-protein kinase Doa; Negative regulator of the copia retrotransposon element of the white (w) gene. In the eye, it is required for normal pigmentation, photoreceptor cell development and for organization of interommatidial bristles. Also essential for embryonic segmentation and differentiation of the nervous system. Functions in the control of alternative splicing by phosphorylating the arginine/serine-rich splicing factors, SR proteins; Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. Lammer subfamily.

Z band alternatively spliced PDZ-motif protein 52 (Zasp52) encodes a member of the Zasp protein family. It is a scaffold protein that binds the product of Actn and localizes to muscle attachment sites and Z-discs in muscle cells, as well as localizing cortically in non-muscle cells. It plays a role in muscle development, especially in myofibril assembly.

SNF4/AMP-activated protein kinase gamma subunit (SNF4Agamma) encodes a protein involved in lipid metabolism, autophagy and response to starvation.

Hephaestus, isoform Y; Hephaestus (heph) encodes a nucleo-cytoplasmic shuttling protein that regulates osk mRNA translation. It is involved in spermatid individualization and Notch signalling regulation.

Par-1 (par-1) encodes a protein kinase involved in multiple processes, including microtubule cytoskeleton organization, axis specification and cell polarity. It regulates hippo signaling and osk mRNA localization.

Stardust, isoform G; Stardust (sdt) encodes membrane-associated guanylate kinase (MAGUK) protein involved in the maintenance of apico-basal cell polarity and the organization of zonula adherens; Belongs to the MAGUK family.

PAR-domain protein 1 (Pdp1) encodes a member of the PAR domain bZip family of sequence-specific transcription factors. it regulates gene expression in muscles and in circadian clock neurons.
