- lithium:proton antiporter activity
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: Li+(in) + H+(out) = Li+(out) + H+(in).
- cellular response to lithium ion
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lithium (Li+) ion stimulus.
- response to lithium ion
Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a lithium (Li+) ion stimulus.
- ribonuclease M5 activity
Catalysis of the endonucleolytic cleavage of RNA, removing 21 and 42 nucleotides, respectively, from the 5'- and 3'-termini of a 5S-rRNA precursor.
- glycoside-pentoside-hexuronide:cation symporter activity
Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: (glycoside, pentoside or hexuronide)(out) + monovalent cation(out) = (glycoside, pentoside or hexuronide)(in) + monovalent cation(in). The cation is Na+, Li+ or H+.
- CAP-Gly domain binding
Binding to a CAP-Gly domain of a protein. The CAP_Gly domain is a conserved, glycine-rich domain of about 42 residues found in some cytoskeleton-associated proteins, and features a novel protein fold containing three beta-sheets.
- encapsulin nanocompartment
Intracellular non-membrane bound organelle, consisting of proteinaceous polyhedral shells that encapsulate enzymes, protecting the contents from their surrounding milieu and/or the milieu from reactants in their interior. The self-assembling, 25-42 nm nanocompartment shell, unlike larger bacterial microcompartments, is made of only one protein, and has only a few proteins inside. Shells about vary from about 25-42 nm in diameter. The shell protein has an HK97-like fold and probably evolved from a viral protein. Artificial encapsulin nanocompartments can be expressed and filled with cargo proteins for biotechnological uses. They are found in many bacterial and a few archaeal phyla.
- amyloid-beta complex
Protein complex involved in modulation of signaling and synaptic function in the brain, predominantly in the cerebral cortex and hippocampus. Forms dimers and multimers of amyloid beta peptide 40 and peptide 42 (proteolytic cleavage products of amyloid beta A4 protein, also known as amyloid beta precursor protein). Mostly found in the extracellular space with a proportion occurring as membrane-bound species. Influences synaptic plasticity through various receptors, mediates dendritic spine loss leading to decreased synapse density, inhibits long-term potentiation (LTP) and enhances long-term depression (LTD). Soluble multimeric form is the main pathogenic species linked to Alzheimer's disease.
