U1 snRNP is the first snRNP to interact with pre-mRNA. This interaction is required for the subsequent binding of U2 snRNP and the U4/U6/U5 tri-snRNP. SNRPA binds stem loop II of U1 snRNA. In a snRNP-free form (SF-A) may be involved in coupled pre-mRNA splicing and polyadenylation process. May bind preferentially to the 5'-UGCAC-3' motif on RNAs. {ECO:0000269|PubMed:9848648}. |RRM 1| |U1 snRNP binding| |U1 snRNA binding| |U1 snRNP| |regulation of mRNA polyadenylation| |regulation of mRNA 3-end processing| |spliceosomal complex| |regulation of mRNA processing| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions| |regulation of mRNA metabolic process| |RNA splicing| |mRNA processing| |mRNA metabolic process| |RNA processing| |identical protein binding| |RNA binding| |RNA metabolic process| |gene expression| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp90|WYE-354 6μM R02 exp90]]|-1.81| |[[:results:exp3|Actinomycin-D 0.001μM R00 exp3]]|1.94| |[[:results:exp485|GSK626616 14μM R08 exp485]]|2.01| |[[:results:exp35|TRAIL 5ng/ml R00 exp35]]|2.37| |[[:results:exp36|TRAIL 50ng/ml R00 exp36]]|2.5| |[[:results:exp365|I-BRD9 4μM R07 exp365]]|3.42| ^Gene^Correlation^ |[[:human genes:h:hars|HARS]]|0.449| |[[:human genes:s:spop|SPOP]]|0.436| Global Fraction of Cell Lines Where Essential: 2/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|1/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 1781 * **Expression level (log2 read counts)**: 6.62 {{:chemogenomics:nalm6 dist.png?nolink |}}
