CATALOGUE NUMBER

PRO-994

SYNONYMS

Small nuclear ribonucleoprotein Sm D1, Sm-D1, Sm-D autoantigen, snRNP core protein D1, SNRPD1, SMD1, SNRPD, HsT2456.

INTRODUCTION

SNRPD1 is a small nuclear ribonucleoprotein which is a member of the SNRNP core protein family. SNRPD1 may act as a charged protein scaffold to stimulate SNRNP assembly or strengthen SNRNP-SNRNP interactions via nonspecific electrostatic contacts with RNA. In the autoimmune disease systemic lupus erythematosus, antinuclear antibodies are developed with Sm specificity.

DESCRIPTION

SNRPD1 Human Recombinant produced in SF9 is a glycosylated, polypeptide chain having a calculated molecular mass of 14,306 Dalton. 
SNRPD1 is expressed with a -6x His tag at N-terminus and purified by proprietary chromatographic techniques.

SOURCE

Sf9 insect cells.
