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; mating; and reproductive structure development. Located in nucleus and polytene chromosome band. Is expressed in several structures, including abdomen; epithelium; extended germ band embryo; parasegment; and reproductive system. Human ortholog(s) of this gene implicated in radioulnar synostosis. Orthologous to several human genes including HOXA11 (homeobox A11) and HOXD11 (homeobox D11). [provided by Alliance of Genome Resources, Apr 2022]

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.
