SnRNP70

snRNP70 also known as U1 small nuclear ribonucleoprotein 70 kDa is a is_associated_with::protein that in humans is encoded by the SNRNP70 is_associated_with::gene. snRNP70 is a small nuclear ribonucleoprotein that associates with is_associated_with::U1 spliceosomal RNA, forming part of the is_associated_with::spliceosome.

Interactions
snRNP70 has been shown to interact with is_associated_with::ASF/SF2, is_associated_with::SRPK1,   and is_associated_with::ZRANB2.

Role in autoimmunity
Antibodies towards snRNP70 are associated with is_associated_with::mixed connective tissue disease.
