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.

Interactions

snRNP70 has been shown to interact with ASF/SF2, [10] [11] SRPK1, [12] [13] and ZRANB2. [14]

Role in autoimmunity

Antibodies towards snRNP70 are associated with mixed connective tissue disease. [15]
