Summary: Enables sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including establishment of mitotic spindle orientation; hindbrain development; and neural keel formation. Located in nucleus. Is expressed in several structures, including germ ring; mesoderm; neural keel; neural plate; and presumptive neural plate. Orthologous to human HOXB1 (homeobox B1).

What's a GeneRIF?

Loss of hoxb1b together with pbx4 reverts the hindbrain to a groundstate identity, demonstrating the importance of hox genes in patterning nearly the entire hindbrain, and a key requirement for Pbx in this process. Additionally, we provide evidence that while pbx genes regulate RA signaling, hoxb1b regulates hindbrain identity through complex regulation of FGF signaling
Title: Coordinate regulation of retinoic acid synthesis by pbx genes and fibroblast growth factor signaling by hoxb1b is required for hindbrain patterning and development.
Data suggest that, in developing gastrula, Znfl1 controls developmental gene expression of Hoxb1b in embryonic posterior neuroectoderm by acting upstream of Pou5f3 and Sall4; these proteins appear to be involved in neurogenesis. (Znfl1 = zinc finger-like gene 1; Hoxb1b = homeobox B1b protein; Pou5f3 = POU domain class 5 transcription factor 3; Sall4 = spalt-like transcription factor 4)
Title: Zebrafish Znfl1 proteins control the expression of hoxb1b gene in the posterior neuroectoderm by acting upstream of pou5f3 and sall4 genes.
Data indicate that hox genes hoxb1a and hoxb1b have separate functions in hindbrain development.
Title: Targeted germ line disruptions reveal general and species-specific roles for paralog group 1 hox genes in zebrafish.
Hoxb1b regulates mitotic spindle rotation during the oriented neural keel symmetric mitoses that are required for normal neural tube lumen formation in the zebrafish.
Title: Hoxb1b controls oriented cell division, cell shape and microtubule dynamics in neural tube morphogenesis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
