Description

General description

Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (UniProt: Q6P5D8; also known as SMC hinge domain-containing protein 1) is encoded by the Smchd1 (also known as Kiaa0650) gene (Gene ID: 74355) in murine species. SMCHD1 is a homodimeric, non-canonical member of the structural maintenance of chromosomes (SMC) protein family that plays a key role in epigenetic silencing by regulating chromatin architecture. It is shown to be essential for X chromosome inactivation. It is recruited to inactivated chromosome X by Xist RNA and acts by mediating the merge of chromatin compartments. It is reported to localize to the inactive X via the XistHnrnpK-polycomb repressive complex 1 pathway. In addition to its role in X inactivation, it also plays a role in the expression of several autosomal gene clusters that are subject to monoallelic expression. It promotes heterochromatin formation in both autosomes and chromosome X, probably by mediating the merge of chromatin compartments. SMCHD1 also plays a role in DNA repair. It localizes to sites of DNA double-strand breaks in response to DNA damage to promote the repair of DNA double-strand breaks. It acts by promoting non-homologous end joining and inhibiting homologous recombination repair. Heterozygous mutations in Smchd1 gene have been linked to facioscapulohumeral muscular dystrophy 2, an inherited muscular weakness syndrome. (Ref.: Jansz, N., et al. (2018).

Specificity

Clone 2B8 is a rat monoclonal antibody that detects SMC hinge domain-containing protein 1 (SMCHD1). It targets an epitope within the ATPase activity domain in the N-terminal half.

Immunogen

Recombinant fragment corresponding to 592 amino acids from the ATPase activity domain from the N-terminal half of murine Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (SMCHD1).

Application

Quality Control Testing

Evaluated by Western Blotting in lysate from wild-type Mouse neuronal stem cells.

Western Blotting Analysis (WB): A 1:500 dilution of this antibody detected Structural maintenance of chromosomes flexible hinge domain-containing protein 1 (SMCHD1) in lysate from wild-type Mouse neuronal stem cells, but not in Smchd1 null cells.

Tested Applications

Western Blotting Analysis: A representative lot detected SMCHD1 in Western Blotting applications (Jansz, N., et. al. (2018). Cell Rep. 25(7):1912-1923).

Immunofluorescence Analysis: A representative lot detected SMCHD1 in Immunofluorescence applications (Jansz, N., et. al. (2018). Cell Rep. 25(7):1912-1923).

Immunoprecipitation Analysis: A representative lot immunoprecipitated SMCHD1 in Immunoprecipitation applications (Jansz, N., et. al. (2018). Cell Rep. 25(7):1912-1923).

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
