The chemical reactions of homocysteine, the amino acid alpha-amino-gamma-mercaptobutanoic acid. Homocysteine is an important intermediate in the metabolic reactions of its S-methyl derivative, methionine.

Catalysis of the hydrolysis of acetyl groups from histones, proteins complexed to DNA in chromatin and chromosomes.

Catalysis of the reaction: H+(out) + drug(in) = H+(in) + drug(out).

Progression through the first phase of meiosis, in which cells divide and homologous chromosomes are paired and segregated from each other, producing two daughter cells.

Catalysis of the reaction: holocytochrome c = apocytochrome c + heme.

The process by which replicated homologous chromosomes are physically separated into two sets during mitosis. Each replicated chromosome, composed of two sister chromatids, aligns at the cell equator, paired with its homologous partner. One homolog of each morphologic type goes into each of the resulting chromosome sets.

Progression through prophase of meiosis I; divided into several stages.

Catalysis of the reaction: 2-hydroxybutane-1,2,4-tricarboxylate = but-1-ene-1,2,4-tricarboxylate + H2O.

Catalysis of the hydrolysis of the Gly76-Lys48 isopeptide bond of polyubiquitin.

homologous chromosome pairing at meiosis

The side by side pairing and physical juxtaposition of homologous chromosomes at the metaphase plate.

The membrane surrounding a synaptic vesicle.

A microtubule-based process that occurs only during M phase of the cell cycle.

regulation of synaptic growth at neuromuscular junction

Any process that modulates the frequency, rate or extent of synaptic growth at neuromuscular junctions.

The process by which antigen-presenting cells express antigen (protein/peptide/lipid) on their cell surface in a form recognizable by lymphocytes.

The process by which antigen-presenting cells express self antigen on their cell surface in a form recognizable by lymphocytes.

Interacting selectively with two or more protein molecules, or a protein and another macromolecule or complex, simultaneously, thereby physically linking the bound proteins or complexes to each other.
