Survival motor neuron protein (SMN); This family consists of several eukaryotic survival motor neuron (SMN) proteins. The Survival of Motor Neurons (SMN) protein, the product of the spinal muscular atrophy-determining gene, is part of a large macromolecular complex (SMN complex) that functions in the assembly of spliceosomal small nuclear ribonucleoproteins (snRNPs). The SMN complex functions as a specificity factor essential for the efficient assembly of Sm proteins on U snRNAs and likely protects cells from illicit, and potentially deleterious, non-specific binding of Sm proteins to RNAs. The actual alignment was detected with superfamily member pfam06003: Pssm-ID: 428716 [Multi-domain] Cd Length: 264 Bit Score: 90.06 E-value: 7.30e-22

Tudor domain found in survival motor neuron protein (SMN), motor neuron-related-splicing factor 30 (SPF30), and similar proteins; This group contains SMN, SPF30, Tudor domain-containing protein 3 (TDRD3), DNA excision repair protein ERCC-6-like 2 (ERCC6L2), and similar proteins. SMN, also called component of gems 1, or Gemin-1, is part of a multimeric SMN complex that includes spliceosomal Sm core proteins and plays a catalyst role in the assembly of small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. SPF30, also called 30 kDa splicing factor SMNrp, SMN-related protein, or survival motor neuron domain-containing protein 1 (SMNDC1), is an essential pre-mRNA splicing factor required for assembly of the U4/U5/U6 tri-small nuclear ribonucleoprotein into the spliceosome. TDRD3 is a scaffolding protein that specifically recognizes and binds dimethylarginine-containing proteins. ERCC6L2, also called DNA repair and recombination protein RAD26-like (RAD26L), may be involved in early DNA damage response. It regulates RNA Pol II-mediated transcription via its interaction with DNA-dependent protein kinase (DNA-PK) to resolve R loops and minimize transcription-associated genome instability. Members of this group contain a single Tudor domain. The Tudor domain binds to proteins with dimethylated arginine or lysine residues, and may also bind methylated histone tails to facilitate protein-protein interactions.

C-terminal oligomerization domain of the Survival Motor Neuron family; The survival motor neuron (SMN) protein family includes metazoan SMN and fungal SMN-like protein 1 (SMN1). SMN forms the oligomeric core of a multiprotein complex, called the SMN complex, that functions in the assembly and biogenesis of small nuclear ribonucleoproteins (snRNPs), the building blocks of the spliceosome. It is expressed in all tissues of metazoan organisms, but is particularly expressed at high levels in motor neurons. Schizosaccharomyces pombe SMN1 is essential for viability and has been shown to interact with human SMN and Sm proteins. Loss of function mutations in the SMN gene of humans cause spinal muscular atrophy (SMA), a leading genetic cause of infant mortality. While most eukaryotes have a single copy of the SMN gene, humans have two; the telomeric SMN1 gene is deleted or mutated in SMA patients, whereas the centromeric SMN2 gene is unaffected and can be present in multiple copies. SMN has three highly conserved domains: a short N-terminal region that is responsible for binding with high affinity to Gemin2; a central Tudor domain that recognizes symmetric dimethylarginine (sDMA) modifications in arginine/glycine rich regions of a number of proteins involved in RNA processing, including the Sm proteins; and a C-terminal domain called the YG-box that is primarily responsible for oligomerization. This model represents the C-terminal oligomerization domain of SMN family proteins. Pssm-ID: 439368 Cd Length: 29 Bit Score: 55.54 E-value: 4.47e-11

Tudor domain found in Tudor domain-containing protein 3 (TDRD3) and similar proteins; TDRD3 is a scaffolding protein that specifically recognizes and binds dimethylarginine-containing proteins. In the nucleus, it acts as a coactivator; it recognizes and binds asymmetric dimethylation on the core histone tails associated with transcriptional activation (H3R17me2a and H4R3me2a) and recruits proteins at these arginine-methylated loci. In the cytoplasm, it may play a role in the assembly and/or disassembly of mRNA stress granules and in the regulation of translation of target mRNAs by binding Arg/Gly-rich motifs (GAR) in dimethylarginine-containing proteins. TDRD3 contains one Tudor domain. The Tudor domain binds to proteins with dimethylated arginine or lysine residues, and may also bind methylated histone tails to facilitate protein-protein interactions.
