- katanin complex
A complex possessing an activity that couples ATP hydrolysis to the severing of microtubules; usually a heterodimer comprising a catalytic subunit (often 60kDa) and a regulatory subunit (often 80 kDa).
- death receptor binding
Binding to a member of the death receptor (DR) family. The DR family falls within the tumor necrosis factor receptor superfamily and is characterized by a cytoplasmic region of ~80 residues termed the death domain (DD).
- FHA domain binding
Binding to a FHA domain of a protein. The FHA domain is a phosphopeptide recognition domain found in many regulatory proteins, and consists of approximately 80-100 amino acid residues folded into an 11-stranded beta sandwich.
- INO80-type complex
A chromatin remodeling protein complex initially purified from S. cerevisiae and containing more than 10 subunits, including the SWR1-related complexes. INO80 (inositol requiring 80)-type complexes have diverse functions, including promoting transcriptional activation and DNA repair.
- photosystem II assembly
The aggregation, arrangement and bonding together of a set of components to form a photosystem II complex on the thylakoid membrane. The photosystem II complex consists of at least 20 polypeptides and around 80 cofactors in most organisms.
- synaptic vesicle, resting pool
A synaptic vesicle belonging to the pool that remain unreleased even after prolonged stimulation causes a saturating degree of vesicular turnover. 50-80% of the total number of synaptic vesicles at a resting terminal bouton are in this pool.
- very-low-density lipoprotein particle binding
Binding to a very-low-density lipoprotein particle, a triglyceride-rich lipoprotein particle that is typically composed of APOB100, APOE and APOCs and has a density of about 1.006 g/ml and a diameter of between 20-80 nm.
- T=9 icosahedral viral capsid
The protein coat that surrounds the infective nucleic acid in some virus particles where the subunits (capsomeres) are arranged to form an icosahedron with T=9 symmetry. The T=9 capsid is composed of 12 pentameric and 80 hexameric capsomeres.
- Ku70:Ku80 complex
Heterodimeric protein complex composed of a 70 kDa and a 80 kDa subunit, binds DNA through a channel formed by the heterodimer. Functions in DNA double stranded break repair, chromosome maintenance, transcription regulation, V(D)J recombination, and activation of DNA-PK.
- ciliary rootlet
A cytoskeleton-like structure, originating from the basal body at the proximal end of a cilium, and extending proximally toward the cell nucleus. Rootlets are typically 80-100 nm in diameter and contain cross striae distributed at regular intervals of approximately 55-70 nm.
