nucleus accumbens associated 1, BEN and BTB (POZ) domain containing

This gene encodes a member of the BTB/POZ protein family. BTB/POZ proteins are involved in several cellular processes including proliferation, apoptosis and transcription regulation. The encoded protein is a transcriptional repressor that plays a role in stem cell self-renewal and pluripotency maintenance. The encoded protein also suppresses transcription of the candidate tumor suppressor Gadd45GIP1, and expression of this gene may play a role in the progression of multiple types of cancer. A pseudogene of this gene is located on the short arm of chromosome 9. [provided by RefSeq, Feb 2012]

sperm protein associated with the nucleus, X-linked, family member A1

Temporally regulated transcription and translation of several testis-specific genes is required to initiate the series of molecular and morphological changes in the male germ cell lineage necessary for the formation of mature spermatozoa. This gene is a member of the SPANX family of cancer/testis-associated genes, which are located in a cluster on chromosome X. The SPANX genes encode differentially expressed testis-specific proteins that localize to various subcellular compartments. This particular gene maps to chromosome X in a head-to-head orientation with SPANX family member A2, which appears to be a duplication of the A1 locus. The protein encoded by this gene targets to the nucleus where it associates with nuclear vacuoles and the redundant nuclear envelope. Based on its association with these poorly characterized regions of the sperm nucleus, this protein provides a biochemical marker to study unique structures in spermatazoa while attempting to further define its role in spermatogenesis.

sperm protein associated with the nucleus on the X chromosome B/F

nucleus accumbens associated 1, BEN and BTB (POZ) domain containing pseudogene

endoplasmic reticulum to nucleus signaling 2

Enables several functions, including ATP binding activity; magnesium ion binding activity; and protein serine/threonine kinase activity. Involved in several processes, including apoptotic chromosome condensation; negative regulation of DNA-templated transcription; and rRNA catabolic process. Located in cytosol and endoplasmic reticulum. [provided by Alliance of Genome Resources, Mar 2025]

endoplasmic reticulum to nucleus signaling 1

This gene encodes the transmembrane protein kinase inositol-requiring enzyme 1. The encoded protein contains two functional catalytic domains, a serine/threonine-protein kinase domain and an endoribonuclease domain. This protein functions as a sensor of unfolded proteins in the endoplasmic reticulum (ER) and triggers an intracellular signaling pathway termed the unfolded protein response (UPR). The UPR is an ER stress response that is conserved from yeast to mammals and activates genes involved in degrading misfolded proteins, regulating protein synthesis and activating molecular chaperones. This protein specifically mediates the splicing and activation of the stress response transcription factor X-box binding protein 1. [provided by RefSeq, Aug 2017]

histone linker H1 domain, spermatid-specific 1, pseudogene

This locus is the ortholog of a mouse protein-coding gene that displays characteristics of a linker histone and is expressed in nuclei of late maturing spermatids. The human locus is expressed; however, the open reading frame has been disrupted by a frameshift so it is unlikely to encode a functional protein. [provided by RefSeq, Oct 2008]

theg spermatid protein

This gene is specifically expressed in the nucleus of haploid male germ cells. The orthologous gene in mice encodes a protein that may play a role in protein assembly through interactions with T-complex protein 1 subunit epsilon. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Nov 2011]
