CC -!- FUNCTION: Transcriptional regulator within D-type neurons that controls
CC terminal differentiation (PubMed:7997265). Required for the development
CC and function of the 19 inhibitory GABAergic (gamma-aminobutyric-acid-
CC secreting) D-type motor neurons, which control locomotion
CC (PubMed:7997265). Plays a role in regulating synapse formation in
CC dorsal D (DD) and ventral D (VD) GABAergic motor neurons, possibly in
CC part by regulating the expression of the neural regulator oig-1
CC (PubMed:26083757). Also required for expression of flp-13 in DD motor
CC neurons (PubMed:15882588). Plays a role in respecification of DD motor
CC neurons through regulation of genes involved in the modulation of
CC cellular cAMP including pde-4 which hydrolyzes cAMP and acy-1 which
CC catalyzes cAMP formation (PubMed:29033363).

CC Event=Alternative splicing; Named isoforms=2;

CC IsoId=P52906-1; Sequence=Displayed;
CC Name=a;
CC IsoId=P52906-2; Sequence=VSP_020103;
CC -!- TISSUE SPECIFICITY: Expressed in D-type GABAergic motor neurons at high
CC levels in young larvae, in which the motor circuitry is formed, and at
CC low levels in older animals (PubMed:7997265). Also present in six non-
CC GABAergic motor neurons and is absent from the seven non-D-type
CC GABAergic neurons (PubMed:7997265). Expressed in DD GABAergic motor
CC neurons and VD GABAergic motor neurons (PubMed:15882588,
CC PubMed:26083757, PubMed:29033363). {ECO:0000269|PubMed:15882588,

CC ECO:0000269|PubMed:7997265}.
CC -!- DISRUPTION PHENOTYPE: Aberrant synaptic connectivity of dorsal and
CC ventral D-type motor neurons onto ventral and dorsal muscle.
CC {ECO:0000269|PubMed:26083757}.
CC -!- SIMILARITY: Belongs to the paired homeobox family. Bicoid subfamily.
