Summary: Enables DNA-binding transcription factor activity and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including genital disc development; male pigmentation; and reproductive structure development. Located in nucleus and polytene chromosome band. Is expressed in several structures, including adult posterior abdominal ganglion neurons; anterior-posterior subdivision of organism; epithelium; genital disc; and somatic trunk mesoderm derivative. Human ortholog(s) of this gene implicated in congenital vertical talus and radioulnar synostosis. Orthologous to several human genes including HOXA10 (homeobox A10) and HOXC10 (homeobox C10).

Boundary bypass activity in the abdominal-B region of the Drosophila bithorax complex is position dependent and regulated.
Title: Boundary bypass activity in the abdominal-B region of the Drosophila bithorax complex is position dependent and regulated.
The Drosophila Fab-7 boundary modulates Abd-B gene activity by guiding an inversion of collinear chromatin organization and alternate promoter use.
Title: The Drosophila Fab-7 boundary modulates Abd-B gene activity by guiding an inversion of collinear chromatin organization and alternate promoter use.
Redundant enhancers in the iab-5 domain cooperatively activate Abd-B in the A5 and A6 abdominal segments of Drosophila.
Title: Redundant enhancers in the iab-5 domain cooperatively activate Abd-B in the A5 and A6 abdominal segments of Drosophila.
The capacity of Abdominal-B to use the sex-specific isoform of Dsx as a cofactor underlines the possibility that these two classes of protein are capable of cooperating in selection and regulation of target genes in a tissue- and sex-specific manner
Title: The Hox gene Abdominal-B uses Doublesex(F) as a cofactor to promote neuroblast apoptosis in the Drosophila central nervous system.
complete reconstitution of bypass and blocking functions
Title: Complete reconstitution of bypass and blocking functions in a minimal artificial Fab-7 insulator from Drosophila bithorax complex.
Data report that the repression of Abd-B, in cyst stem cells (CySCs) is essential for the homeostasis and cell identity maintenance in the adult Drosophila testis. Derepression of Abd-B in CySCs disrupts the proper self-renewal of both germline stem cells (GSCs) and CySCs, and leads to an excessive expansion of early stage somatic cells, which originate from both lineages.
Title: Repression of Abd-B by Polycomb is critical for cell identity maintenance in adult Drosophila testis.
iab-7 polycomb response element (PRE) functions as a component of the Fab-7 boundary. The boundary activity of the iab-7 PRE sequence depends upon a complex called the LBC, LBC is a multiprotein complex that contains at least three distinct DNA binding proteins, the GAGA factor (GAF), Clamp, and Mod(mdg4).
Title: The bithorax complex iab-7 Polycomb response element has a novel role in the functioning of the Fab-7 chromatin boundary.
analysis of blocking and bypass activities of the Fab-8 boundary in the Drosophila bithorax complex
Title: Functional Dissection of the Blocking and Bypass Activities of the Fab-8 Boundary in the Drosophila Bithorax Complex.
Abd-B is required in neurons during development for females to become highly receptive to male courtship. Abd-B neurons control pausing, a key aspect of female sexual receptivity, in response to male courtship.
Title: Abdominal-B neurons control Drosophila virgin female receptivity.
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.
