Summary: Enables DNA binding activity. Involved in several processes, including cerebellar cortex morphogenesis; neural precursor cell proliferation; and regulation of cell population proliferation. Located in nucleus. Colocalizes with euchromatin. Is expressed in several structures, including bone; central nervous system; dorsal root ganglion; sensory organ; and submandibular gland primordium. Orthologous to human TRNP1 (TMF1 regulated nuclear protein 1). [provided by Alliance of Genome Resources, Dec 2024]

Trnp1 organizes diverse nuclear membrane-less compartments in neural stem cells.
Title: Trnp1 organizes diverse nuclear membrane-less compartments in neural stem cells.
Data suggest that neurons in mouse brain exhibit DNA sequence encoding protein precursor, proMexneurin, that contains three peptide sequences: Mexneurin-1 (an endomorphin1-like peptide), Mexneurin-2 (an endomorphin1-like peptide), and Mexneurin-3 (peptide which appears to be unrelated to endomorphins); neurons exhibit expression of proMexneurin mRNA throughout mouse brain.
Title: Mexneurin is a novel precursor of peptides in the central nervous system of rodents.
Study identified Trnp1 as a regulator of mammalian brain development and as a key factor controlling neocortical expansion. Trnp1 levels have striking effects on tangential, radial, and lateral expansion of the cerebral cortex.
Title: Trnp1 regulates expansion and folding of the mammalian cerebral cortex by control of radial glial fate.

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.
