Spinal muscular atrophy (SMA) is a common fatal autosomal recessive disorder characterized by the degeneration of motor neurons and muscular atrophy. A gene called Survival of Motor Neurons (SMN) has been identified as the determining gene in SMA and is deleted or mutated in greater than 98% of SMA patients. The SMN protein localizes to both the cytoplasm and the nucleus. In the nucleus, SMN has been found to localize in a nuclear structure termed gems for Gemini of coiled bodies, which contain high levels of small ribonucleoproteins (snRNPs). SMN forms complexes with proteins including SIP1, Gemin 2-7 and several others known to be involved in the biogenesis of snRNPs. SMN antibodies may serve as a useful research tool to study SMN complexes and gems, and their role in pre-RNA processing and RNA metabolism.

FAQs for SMN Antibody (NB100-1936). (Showing 1 - 1 of 1 FAQs).

  1. Could you recommond the Human specific SMN antibody? It will only recognize human SMN, without cross reaction with mouse smn.
    • We do not have an SMN antibody that has been validated NOT to work in mouse samples. When an antibody is found to not react with a certain species, we mark the data sheet with a (-) next to the species' name. Unfortunately, the SMN antibodies that do not list mouse have not been tested in mouse, and may react.
