| Application: | Mouse monoclonal clone 2B1 anti-SMN antibody is an important tool for studying the role of the survival of motor neurons protein in nuclear processes and spinal muscular atrophy (SMA). It may be used in immunoblotting (~35 kDa), immunoprecipitation, and immunocytochemistry. |
| Biochem/physiol Actions: | Survival of Motor Neurons (SMN) complex is important in various biological processes, such as assembly and restructuring of spliceosomal small nuclear ribonucleoproteins (snRNPs), pre mRNA splicing and transcription. Spinal muscular atrophy (SMA) is caused by reduced expression or mutations in the survival of motor neurons (SMN) protein. Deletion or mutation in the telomeric copy (SMN1) causes the SMA phenotype. The severity of SMA is in direct correlation with the expression level of the SMN protein, either from the SMN1 gene or a different spliced form of SMN from the SMN2 gene. The SMN complex interacts with various protein substrates such as Sm and Lsm proteins of the spliceosomal snRNPs, fibrillarin, GAR1, RNA helicase A, the human hnRNP proteins (hnRNPQ, U and R), coilin and p53. |
| Biochem/physiol Actions: | The antibody recognizes human, mouse, and Xenopus SMN. |
