Description

General description

The survival of motor neurons (SMN) protein is essential for the biogenesis of small nuclear RNA (snRNA)-ribonucleoproteins (snRNPs), the major components of the pre-mRNA splicing machinery. Though it is ubiquitously expressed, SMN deficiency causes the motor neuron degenerative disease spinal muscular atrophy (SMA). SMN deficiency has unexpected cell type-specific effects on the repertoire of snRNAs and mRNAs. It alters the stoichiometry of snRNAs and causes widespread pre-mRNA splicing defects in numerous transcripts of diverse genes, preferentially those containing a large number of introns, in SMN-deficient mouse tissues. The SMN complex plays a role in RNA metabolism and in splicing regulation.

~35 kDa was observed; however, the calculated molecular weight is 31.849 kDa

Immunogen

Epitope: Unknown

Histidine-tagged recombinant protein corresponding to human SMN.

Application

RNA Binding Protein Immunoprecipitation:
Representative lot data.
RIP Lysate prepared from HeLa cells (~2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using either 5 µg of a normal mouse IgG or 5 µg of Anti-SMN antibody and the Magna RIP^® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of SMN-associated RNA was verified by qPCR using primers specific for human collagen alpha type 1 mRNA (Please see figures).
Please refer to the Magna RIP (Cat. # 17-700) or EZ-Magna RIP (Cat. # 17-701) protocol for experimental details.

Western Blot Analysis:
Representative lot data.
HeLa cell lysate was resolved by electrophoresis, transferred to PVDF membranes and probed with anti-SMN at a 0.5 µg/mL dilution.
Proteins were visualized using a goat anti-mouse IgG conjugated to HRP using a chemiluminescence detection system.
Arrow indicates SMN (~35 kDa) (Please see figures).

Immunocytochemistry Analysis:
Representative lot data.
A 1:500 dilution from a representative lot detected SMN in HeLa cells (Please see figures).
