C2H2 ZINC FINGER TRANSCRIPTION FACTORS -
Zinc finger C2H2 transcription factors are sequence-specific DNA binding proteins that regulate transcription. They possess DNA-binding domains that are formed from repeated Cys2His2 zinc finger motifs. (Adapted from PMID:1835093, FBrf0220103 and FBrf0155739).
ZINC FINGER HOMEOBOX TRANSCRIPTION FACTORS -
Zinc finger homeobox transcription factors are sequence-specific DNA binding proteins that regulate transcription. This class includes proteins with homeodomain and C2H2 and C2H2-like zinc finger motifs. (Adapted from FBrf0232555 and PMID:18797923).

Additional Descriptive Data
In 2nd instar larvae the zfh2 domain is broader than but includes the nub and rn domains in the presumptive wing. Later it corresponds to the wing hinge. The zfh2 expression domain is largely complementary to the dve and nab domains during larval development.
Markers that uniquely identify the cells of the NB3-7 lineage were used to examine the serotonin expressing cell lineages.
zfh2 is expressed in the lateral, but not the medial, of the paired ventro-lateral serotonergic neurons.
zfh2 protein isexpressed in about 50 cells/segment in the lateral embryonic CNS atpositions consistent with the subsequent location of serotonin cells. Inlarvae, it is expressed in a dispersed pattern in about 20% of the cellsin the ventral ganglion. A subset of these also express Ddc and includedopamine and seratonin neurons.
zfh2 protein is first detected in the CNS at the middle of germ band retraction. It is present in at least 50 neurons per hemisegment as well as in cells of the brain. It is also detected at lower levels in the hindgut of older embryos

    zfh2 is required for proximal wng development.
    eg is necessary for the maintenance of en and zfh2 expression in the serotonin neurons.
    One of the homeodomain loci identified in a screen for genes encoding DNA binding proteins capable of binding to a consensus Engrailed binding site.
    Assayed in an analysis of chromosome 4 using pulsed field gel electrophoresis.
    Profile of zfh2 expression in the larval CNS shows intriguing overlap with Ddc expression in specific serotonin and dopamine neurons. The product of zfh2 binds to a protein binding site in the Ddc promoter.
    The product of zfh2 possesses three homeodomains and sixteen C2H2 zinc fingers. The novel arrangement of interspersed homeodomain and zinc-finger motifs in the primary sequences of the zfh1 and zfh2 gene products may signify an unusual mechanism of transcriptional regulation by these products.
    The expression pattern of zfh2 suggests that the protein may be involved in neurogenesis.
