Nuclear speckle splicing regulatory protein 1 is a protein that in humans is encoded by the NSRP1 gene.{{cite journal | vauthors = Wiemann S, Weil B, Wellenreuther R, Gassenhuber J, Glassl S, Ansorge W, Bocher M, Blocker H, Bauersachs S, Blum H, Lauber J, Dusterhoft A, Beyer A, Kohrer K, Strack N, Mewes HW, Ottenwalder B, Obermaier B, Tampe J, Heubner D, Wambutt R, Korn B, Klein M, Poustka A | title = Toward a catalog of human genes and proteins: sequencing and analysis of 500 novel complete protein coding human cDNAs | journal = Genome Res | volume = 11 | issue = 3 | pages = 422–35 |date=Mar 2001 | pmid = 11230166 | pmc = 311072 | doi = 10.1101/gr.GR1547R }}{{cite web | title = NSRP1 nuclear speckle splicing regulatory protein 1 [ Homo sapiens (human) ]| url = https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=84081| date =17 June 2024}}
NSRP1 is located within nuclear speckles. Speckles are dynamic membrane-less organelles within the nucleus and are rich in RNA splicing factors.{{Cite journal |last1=Chen |first1=Yu |last2=Belmont |first2=Andrew S. |date=April 2019 |title=Genome organization around nuclear speckles |journal=Current Opinion in Genetics & Development |volume=55 |pages=91–99 |doi=10.1016/j.gde.2019.06.008 |issn=1879-0380 |pmc=6759399 |pmid=31394307}} NSRP1 interacts with other splicing factors including SRSF1 and SRSF2 and modulates pre-mRNA splicing.{{Cite journal |last1=Kim |first1=Young-Dae |last2=Lee |first2=Jung-Yoon |last3=Oh |first3=Kyu-Man |last4=Araki |first4=Masatake |last5=Araki |first5=Kimi |last6=Yamamura |first6=Ken-ichi |last7=Jun |first7=Chang-Duk |date=May 2011 |title=NSrp70 is a novel nuclear speckle-related protein that modulates alternative pre-mRNA splicing in vivo |journal=Nucleic Acids Research |volume=39 |issue=10 |pages=4300–4314 |doi=10.1093/nar/gkq1267 |issn=1362-4962 |pmc=3105421 |pmid=21296756}}{{Cite journal |last1=Kim |first1=Chang-Hyun |last2=Kim |first2=Young-Dae |last3=Choi |first3=Eun-Kyung |last4=Kim |first4=Hye-Ran |last5=Na |first5=Bo-Ra |last6=Im |first6=Sin-Hyeog |last7=Jun |first7=Chang-Duk |date=2016-03-18 |title=Nuclear Speckle-related Protein 70 Binds to Serine/Arginine-rich Splicing Factors 1 and 2 via an Arginine/Serine-like Region and Counteracts Their Alternative Splicing Activity |journal=The Journal of Biological Chemistry |volume=291 |issue=12 |pages=6169–6181 |doi=10.1074/jbc.M115.689414 |issn=1083-351X |pmc=4813587 |pmid=26797131|doi-access=free }} Knockout of the mouse ortholog Nsrp1 resulted in early embryonic lethality.
Humans with biallelic pathogenic variants in NSRP1 have an autosomal recessive condition called neurodevelopmental disorder with spasticity, seizures, and brain abnormalities (NEDSSBA, MIM 620001).{{Cite journal |last1=Calame |first1=Daniel G. |last2=Bakhtiari |first2=Somayeh |last3=Logan |first3=Rachel |last4=Coban-Akdemir |first4=Zeynep |last5=Du |first5=Haowei |last6=Mitani |first6=Tadahiro |last7=Fatih |first7=Jawid M. |last8=Hunter |first8=Jill V. |last9=Herman |first9=Isabella |last10=Pehlivan |first10=Davut |last11=Jhangiani |first11=Shalini N. |last12=Person |first12=Richard |last13=Schnur |first13=Rhonda E. |last14=Jin |first14=Sheng Chih |last15=Bilguvar |first15=Kaya |date=December 2021 |title=Biallelic loss-of-function variants in the splicing regulator NSRP1 cause a severe neurodevelopmental disorder with spastic cerebral palsy and epilepsy |journal=Genetics in Medicine|volume=23 |issue=12 |pages=2455–2460 |doi=10.1038/s41436-021-01291-x |issn=1530-0366 |pmc=8633036 |pmid=34385670}}{{Cite web |title=Entry - #620001 - NEURODEVELOPMENTAL DISORDER WITH SPASTICITY, SEIZURES, AND BRAIN ABNORMALITIES; NEDSSBA - OMIM |url=https://omim.org/entry/620001 |access-date=2023-01-22 |website=omim.org |language=en-us}} Affected individuals have delayed developmental milestones, axial hypotonia, appendicular spasticity, epilepsy, and often microcephaly. Brain abnormalities including under-opercularization, cerebellar atrophy, and thinning of the corpus callosum can be seen. Patients with NEDSSBA often have a clinical diagnosis of spastic cerebral palsy (CP), and thus NEDSSBA should be considered a CP disease gene.
