snRNP70 also known as U1 small nuclear ribonucleoprotein 70 kDa is a protein^[5] that in humans is encoded by the SNRNP70 gene.^[6]^[7] snRNP70 is a small nuclear ribonucleoprotein that associates with U1 spliceosomal RNA, forming the U1snRNP a core component of the spliceosome. The U1-70K protein and other components of the spliceosome complex form detergent-insoluble aggregates in both sporadic and familial human cases of Alzheimer's disease.^[8]^[9] U1-70K co-localizes with Tau in neurofibrillary tangles in Alzheimer's disease.
