Summary: Enables DNA-binding transcription factor activity, RNA polymerase II-specific; DNA-binding transcription factor binding activity; and cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including genital disc development; heart development; and neuroblast differentiation. Located in nucleus and polytene chromosome band. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including anterior-posterior subdivision of organism; epithelium; imaginal disc; ventral intersegmental neurons; and visceral mesoderm derivative. Used to study leukemia. Orthologous to human HOXA6 (homeobox A6). [provided by Alliance of Genome Resources, Dec 2024]

Grh, AbdA, and Exd function together at multiple motifs on the apoptotic enhancer. Exd-Grh-Notch work with different Hox genes through region specific enhancers to pattern respective segments of larval central nervous system.
Title: Combinatorial action of Grainyhead, Extradenticle and Notch in regulating Hox mediated apoptosis in Drosophila larval CNS.
Identification of a two-step mechanism of Hox-driven transcription, with M1BP binding leading to Pol II recruitment followed by AbdA targeting, which results in a change in the chromatin landscape and enhanced transcription.
Title: The Hox proteins Ubx and AbdA collaborate with the transcription pausing factor M1BP to regulate gene transcription.
We also observed that these functions of abd-A are required in its exclusive as well as the coexpression domain with that of Abd-B
Title: Role of abd-A and Abd-B in development of abdominal epithelia breaks posterior prevalence rule.
This "iab-8 RNA" produces a micro RNA to repress abd-A, but also has a second, redundant repression mechanism that acts only "in cis." Transcriptional interference with the abd-A promoter is the most likely mechanism
Title: abd-A regulation by the iab-8 noncoding RNA.
Abdominal-A uses both Pax2-dependent and Pax2-independent mechanisms to stimulate rhomboid Cis-regulatory-modules activity to induce proper oenocyte numbers.
Title: Integration of an abdominal Hox complex with Pax2 yields cell-specific EGF secretion from Drosophila sensory precursor cells.
The results uncover redundancy, interactivity, and multifunctionality of protein domains as salient features underlying overall AbdA protein activity
Title: Insights into Hox protein function from a large scale combinatorial analysis of protein domains.
Data show that the bithorax complex is an approximately 330kb genomic region that is responsible for directing the transcription of three homeotic (Hox) genes Ultrabithorax (Ubx), abdominal-A (abd-A) and Abdominal-B (Abd-B) during embryonic development.
Title: Molecular dissection of cis-regulatory modules at the Drosophila bithorax complex reveals critical transcription factor signature motifs.
Results suggest that the expression of cas is segment-specifically regulated negatively by Ubx and abdA genes, but positively by the AbdB gene.
Title: Drosophila castor is regulated negatively by the Ubx and abdA genes, but positively by the AbdB gene.
