Nuclear autoantigenic sperm protein

NASP, histone H1-binding protein
This gene encodes a H1 histone binding protein that is involved in transporting histones into the nucleus of dividing cells. Multiple isoforms are encoded by transcript variants of this gene. The somatic form is expressed in all mitotic cells, is localized to the nucleus, and is coupled to the cell cycle. The testicular form is expressed in embryonic tissues, tumor cells, and the testis. In male germ cells, this protein is localized to the cytoplasm of primary spermatocytes, the nucleus of spermatids, and the periacrosomal region of mature spermatozoa.

Singla-Pareek et al., In Bmc Plant Biol, 2014
These could be classified into seven different families, namely NAP, CAF1, SPT6, ASF1, HIRA, NASP, and FACT.
Structural insights into yeast histone chaperone Hif1: a scaffold protein recruiting protein complexes to core histones.
Niu et al., In Biochem J, 2014
Yeast Hif1 [Hat1 (histone acetyltransferase 1)-interacting factor], a homologue of human NASP (nuclear autoantigenic sperm protein), is a histone chaperone that is involved in various protein complexes which modify histones during telomeric silencing and chromatin reassembly.
Peptides genetically selected for NF-κB activation cooperate with oncogene Ras and model carcinogenic role of inflammation.
Gudkov et al., Buffalo, United States. In Proc Natl Acad Sci U S A, 2014
Consistent with their ability to cooperate with oncogenic Ras in cell transformation, NASP expression reduced the transactivation activity of p53.
The influence of secondary structure, selection and recombination on rubella virus nucleotide substitution rate estimates.
Harkins et al., Cape Town, South Africa. In Virol J, 2013
We specifically accounted for possible confounders of nucleotide substitution rate estimates, such as temporally biased sampling, sporadic recombination, and natural selection favouring either increased or decreased genetic diversity (estimated by the PARRIS and FUBAR methods), at nucleotide sites within the genomic secondary structures (predicted by the NASP method).
Molecular evolution of NASP and conserved histone H3/H4 transport pathway.
Fillingham et al., Toronto, Canada. In Bmc Evol Biol, 2013
BACKGROUND: NASP is an essential protein in mammals that functions in histone transport pathways and maintenance of a soluble reservoir of histones H3/H4.
Neuronal-specific deficiency of the splicing factor Tra2b causes apoptosis in neurogenic areas of the developing mouse brain.
Wirth et al., Köln, Germany. In Plos One, 2013
TRA2B has been shown to be involved in splicing processes of Nasp (nuclear autoantigenic sperm protein), MAPT (microtubule associated protein tau) and SMN (survival motor neuron), and is therefore implicated in spermatogenesis and neurological diseases like Alzheimer's disease, dementia, Parkinson's disease and spinal muscular atrophy.

These include members of the nucleoplasmin (NPM2/NPM3), which are preferentially associated with histones H2A-H2B in the egg and the nuclear autoantigenic sperm protein (NASP) families.

The insights into NASP function and the existence of a tunable reservoir in mammalian cells demonstrate that contingency is integrated into the histone supply chain to respond to unexpected changes in demand.
Identification of evolutionarily conserved exons as regulated targets for the splicing activator tra2β in development.
Elliott et al., Newcastle upon Tyne, United Kingdom. In Plos Genet, 2011
