Sad1 / UNC-like C-terminal; The C. elegans UNC-84 protein is a nuclear envelope protein that is involved in nuclear anchoring and migration during development. The S. pombe Sad1 protein localizes at the spindle pole body. UNC-84 and and Sad1 share a common C-terminal region, that is often termed the SUN (Sad1 and UNC) domain. In mammals, the SUN domain is present in two proteins, Sun1 and Sun2. The SUN domain of Sun2 has been demonstrated to be in the periplasm.

 92-453 4.94e-48

Mitochondrial RNA binding protein MRP; MRP1 and MRP2 are mitochondrial RNA binding proteins that form a heteromeric complex. The MRP1/MRP2 heterotetrameric complex binds to guide RNAs and stabilizes them in an unfolded conformation suitable for RNA-RNA hybridization. Each MRP subunit adopts a 'whirly' transcription factor fold.

coiled-coil domain 1 of SUN domain-containing protein 1 and similar proteins; SUN domain-containing protein 1 (SUN1), also called protein unc-84 homolog A, or Sad1/unc-84 protein-like 1, is a component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex which is involved in the connection between the nuclear lamina and the cytoskeleton. Besides the core SUN domain, SUN1 contains two coiled-coil domains (CC1 and CC2), which act as the intrinsic dynamic regulators for controlling the activity of the SUN domain. This model corresponds to CC1 that may function as an activation segment to release CC2-mediated inhibition of the SUN domain.

 543-706 1.61e-03

Calcium binding and coiled-coil domain (CALCOCO1) like; Proteins found in this family are similar to the coiled-coil transcriptional coactivator protein coexpressed by Mus musculus (CoCoA/CALCOCO1). This protein binds to a highly conserved N-terminal domain of p160 coactivators, such as GRIP1, and thus enhances transcriptional activation by a number of nuclear receptors. CALCOCO1 has a central coiled-coil region with three leucine zipper motifs, which is required for its interaction with GRIP1 and may regulate the autonomous transcriptional activation activity of the C-terminal region.

Sad1 / UNC-like C-terminal; The C. elegans UNC-84 protein is a nuclear envelope protein that is involved in nuclear anchoring and migration during development. The S. pombe Sad1 protein localizes at the spindle pole body. UNC-84 and and Sad1 share a common C-terminal region, that is often termed the SUN (Sad1 and UNC) domain. In mammals, the SUN domain is present in two proteins, Sun1 and Sun2. The SUN domain of Sun2 has been demonstrated to be in the periplasm.

Mitochondrial RNA binding protein MRP; MRP1 and MRP2 are mitochondrial RNA binding proteins that form a heteromeric complex. The MRP1/MRP2 heterotetrameric complex binds to guide RNAs and stabilizes them in an unfolded conformation suitable for RNA-RNA hybridization. Each MRP subunit adopts a 'whirly' transcription factor fold.

coiled-coil domain 1 of SUN domain-containing protein 1 and similar proteins; SUN domain-containing protein 1 (SUN1), also called protein unc-84 homolog A, or Sad1/unc-84 protein-like 1, is a component of the LINC (LInker of Nucleoskeleton and Cytoskeleton) complex which is involved in the connection between the nuclear lamina and the cytoskeleton. Besides the core SUN domain, SUN1 contains two coiled-coil domains (CC1 and CC2), which act as the intrinsic dynamic regulators for controlling the activity of the SUN domain. This model corresponds to CC1 that may function as an activation segment to release CC2-mediated inhibition of the SUN domain.

 543-706 1.61e-03

Calcium binding and coiled-coil domain (CALCOCO1) like; Proteins found in this family are similar to the coiled-coil transcriptional coactivator protein coexpressed by Mus musculus (CoCoA/CALCOCO1). This protein binds to a highly conserved N-terminal domain of p160 coactivators, such as GRIP1, and thus enhances transcriptional activation by a number of nuclear receptors. CALCOCO1 has a central coiled-coil region with three leucine zipper motifs, which is required for its interaction with GRIP1 and may regulate the autonomous transcriptional activation activity of the C-terminal region.
