Protein attributes

Sequence length	240 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	May be involved in tissue-specific alternative RNA processing events.
Subunit structure	Interacts with TDRD3. Ref.11
Subcellular location	Nucleus.
Tissue specificity	Expressed in brain and lymphoblasts. Ref.10
Miscellaneous	Encoded on a bicistronic transcript that encode for two proteins, SNRPN and SNURF. Patients with the autoimmune disease systemic lupus erythematosus (SLE) have autoantibodies directed against some of the individual snRNP polypeptides. The most common autoantigen is called Sm. N bears Sm epitopes.
Sequence similarities	Belongs to the snRNP SmB/SmN family.
