Non-canonical member of the structural maintenance of chromosomes (SMC) protein family that plays a key role in epigenetic silencing by regulating chromatin architecture (PubMed:26091879, PubMed:29887375). Promotes heterochromatin formation in both autosomes and chromosome X, probably by mediating the merge of chromatin compartments (PubMed:23754746, PubMed:23819640, PubMed:26391951, PubMed:28587678, PubMed:29887375). Plays a key role in chromosome X inactivation in females by promoting the spreading of heterochromatin (PubMed:18425126, PubMed:22841499, PubMed:26391951, PubMed:29887375). Recruited to inactivated chromosome X by Xist RNA and acts by mediating the merge of chromatin compartments: promotes random chromatin interactions that span the boundaries of existing structures, leading to create a compartment-less architecture typical of inactivated chromosome X (PubMed:29887375). Required to facilitate Xist RNA spreading (PubMed:29887375). Also required for silencing of a subset of clustered autosomal loci in somatic cells, such as the DUX4 locus (PubMed:23754746, PubMed:23819640, PubMed:28587678). Has ATPase activity; may participate in structural manipulation of chromatin in an ATP-dependent manner as part of its role in gene expression regulation (PubMed:26391951, PubMed:27059856). Also plays a role in DNA repair: localizes to sites of DNA double-strand breaks in response to DNA damage to promote the repair of DNA double-strand breaks (By similarity). Acts by promoting non-homologous end joining (NHEJ) and inhibiting homologous recombination (HR) repair (By similarity). Required during preimplantation development, probably acts by regulating chromatin architecture (PubMed:29900695).By similarity10 Publications

Defects in Smchd1 are the cause of the MommeD1 (modifier of murine metastable epialleles) phenotype, a semi-dominant suppressor of variegation (PubMed:18425126, PubMed:21553025). Mice display female-specific mid-gestation lethality and hypomethylation of the X-linked gene Hprt1, due to defects in X inactivation (PubMed:18425126, PubMed:21553025, PubMed:23754746). Mice do not show defects on telomeres length (PubMed:18425126, PubMed:21553025). Male mice are less affected, with some surviving to become fertile adults on the FVB/n genetic background (PubMed:18425126). On other genetic backgrounds, all males lacking die perinatally (PubMed:18425126). A subset of clustered autosomal loci display hypomethylation and derepression (PubMed:23754746, PubMed:23819640, PubMed:28587678).5 Publications

Atypical member of the structural maintenance of chromosomes (SMC) protein family (PubMed:26733688, PubMed:27059856). Like other members of the SMC family, has ATPase activity, which is probably necessary for its engagement with chromatin, and a SMC hinge domain (PubMed:26733688, PubMed:27059856). However, the SMC hinge domain adopts an unconventional homodimeric arrangement augmented by an intermolecular coiled coil formed between the two monomers. This suggests that protein may assemble as a head-to-head parallel dimer without adopting a hairpin shape at the hinge domain, unlike the dimeric arrangement conventionally found in other members of the SMC protein family (PubMed:26733688). The SMC hinge domain binds DNA and RNA (PubMed:26091879).3 Publications

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i1A41FC47C54B5415
