AATF leucine zipper-containing domain
The AATF leucine zipper-containing domain (IPR025160) is a conserved leucine zipper domain found in the Apoptosis Antagonizing Transcription Factor AATF, also called Che-1, annotated at residues 233-327 of the human protein.
Activity-regulated cytoskeleton-associated protein, N-terminal domain
Arc_N (IPR045557), the N-terminal domain of the activity-regulated cytoskeleton-associated protein Arc/Arg3.1: a basic, antiparallel coiled-coil domain unique to tetrapods that mediates membrane binding, Arc oligomerization via the 113MHVWREV119 motif, and virus-like capsid formation.
Alanine--tRNA ligase, helical bundle domain
Helical bundle domain of alanyl-tRNA synthetase (AlaRS), a class II aminoacyl-tRNA synthetase; also called the ATL domain. It binds the tRNA(Ala) acceptor stem and recognizes the G3:U70 wobble pair, the 'second genetic code' identity element.
Anillin homology domain
Anillin homology domain (AHD), InterPro IPR012966: conserved C-terminal domain of anillin scaffold proteins (human residues 608-943) that binds RhoA, septins, Ect2, and negatively charged lipids via a cryptic C2-like fold, essential for cleavage-furrow localization and cytokinesis.
CGGC domain
CGGC domain (CDD cl02356) is a putative conserved protein domain containing a highly conserved central CGGC sequence and many conserved cysteines and histidines, suggestive of a zinc binding function, found across cellular organisms.
Cysteine-rich domain
Cysteine-rich domain: protein segments dense in cysteine that bind zinc or iron-sulfur clusters or form disulfide bonds. Covers the Pfam CCG domain (PF02754), RING fingers, Frizzled CRDs, TNFR modules, and disulfide-rich peptides.
DISC1 domain, vertebrates
DISC1 domain, vertebrates: domain organization of the DISC1 scaffold protein (Disrupted in Schizophrenia 1), an 854-aa protein with a disordered N-terminal head, conserved C-terminal coiled-coil tail, and UVR-like repeats, disrupted by the Scottish t(1;11) translocation.
Kinetochore protein Nuf2, N-terminal
Kinetochore protein Nuf2, N-terminal (Pfam PF03800, InterPro IPR005549) is the conserved calponin homology domain of Nuf2, an Ndc80 kinetochore complex subunit that binds spindle microtubules, enables chromosome segregation, and supports ribosome biogenesis.
Methylated-DNA-[protein]-cysteine S-methyltransferase, DNA binding
Methylated-DNA-[protein]-cysteine S-methyltransferase, DNA binding (IPR014048, PF01035) is the C-terminal helix-turn-helix DNA-binding domain of AGT/MGMT/OGT, the suicide DNA repair enzyme that removes O6-alkyl groups from guanine via Cys145.
Mff-like domain
Mff-like domain (InterPro IPR039433), a coiled-coil plus transmembrane domain in mitochondrial fission factor (Mff) and the C terminus of FATE1; in Mff it supports Drp1 recruitment for mitochondrial and peroxisomal fission.
Mis18 domain
Mis18 domain (Yippee-like/MeDiY, IPR034752): conserved zinc-binding N-terminal domain of Mis18 kinetochore proteins; C-X-X-C motifs, dimerization essential for centromere localization and CENP-A loading; absent from Drosophila.
Mitochondria fission protein Fis1, cytosolic domain
Fis1 cytosolic domain: the ~15 kDa soluble TPR-like six-helix bundle of mitochondrial fission protein 1 (FIS1), a tail-anchored outer membrane protein; binds adaptors Mdv1/Caf4 in yeast, Drp1 recruitment contested in mammals, Cys41 redox dimerization.
Pro-like, C-terminal domain
Pro-like, C-terminal domain (ProC-like, C-terminal domain; Pfam Pro_C_rel), CATH superfamily 1.10.1040.20, a mainly-alpha orthogonal-bundle domain at the C-terminus of proline utilization A and related bacterial proteins, non-catalytic but required for PutA active-site integrity.
Putative zinc-finger
Putative zinc-finger (InterPro IPR027383) is a protein domain classification for sequence regions resembling zinc fingers, cysteine/histidine-rich domains binding tetrahedral zinc, whose zinc-binding function is predicted but not experimentally confirmed.
SOGA, coiled-coil domain
SOGA coiled-coil domain (Pfam PF11365, InterPro IPR027881 SOGA_CC): a conserved N-terminal coiled-coil domain of the SOGA family proteins SOGA1, SOGA2/MTCL1, and SOGA3, involved in autophagy regulation and mitotic chromosome segregation.
Staphylococcal nuclease (SNase-like), OB-fold
Staphylococcal nuclease (SNase-like), OB-fold (InterPro IPR016071): a five-stranded beta-barrel protein domain defined by Murzin in 1993, prototyped by the Ca2+-dependent nuclease of Staphylococcus aureus and found across all three kingdoms of life.
Vms1-associating treble clef domain
Vms1-associating treble clef (VTC) domain, InterPro IPR041540: a treble-clef-fold zinc-binding domain of Vms1/VLRF1-family release-factor-like proteins, gained in the ancestor of stramenopiles, plants, amoebozoans, animals, and fungi, possibly lost in budding yeast.
XRCC4, N-terminal domain
XRCC4 N-terminal domain: globular head (residues 1–115) of the human DNA repair protein XRCC4, a β-sandwich with helix-turn-helix motif and new fold; dimerizes XRCC4, binds XLF, and anchors NHEJ double-strand break repair.
Yippee domain
Yippee domain: a ~100-residue eukaryotic protein domain with a C-X(2)-C-X(52)-C-X(2)-C zinc-binding motif, defining the YPEL1-5 family and also found in Mis18 kinetochore and Cereblon (CULT) proteins.
