The process by which an organism retains a population of stem cells, preventing the commitment of all stem cell progeny to a differentiated cell fate.

Catalysis of the hydrolysis of nonterminal peptide linkages in oligopeptides or polypeptides; the optimum reaction pH is below 5 due to an aspartic residue involved in the catalytic process.

positive regulation of cellular biosynthesis

Any process that activates or increases the rate of the transformation of simpler substances into more complex ones, carried out by individual cells.

Any process that modulates the frequency, rate or extent of DNA recombination, the processes by which a new genotype is formed by reassortment of genes resulting in gene combinations different from those that were present in the parents.

Any process that modulates the frequency, rate or extent of lymphocyte proliferation.

The chemical reactions involving any compound containing pteridine (pyrazino(2,3-dipyrimidine)), e.g. pteroic acid, xanthopterin and folic acid.

peptide receptor activity, G-protein coupled

peptide receptor activity, G protein coupled

Formation of the synaptonemal complex, a structure that holds paired chromosomes together during prophase I of meiosis and that promotes genetic recombination.

oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen, NAD or NADH as one donor, and incorporation of one atom of oxygen

Catalysis of the reaction: cation A(out) + cation B(in) = cation A(in) + cation B(out).

Any process that modulates the frequency, rate or extent of DNA recombination during mitosis.

positive regulation of lymphocyte proliferation

Any process that activates or increases the rate or extent of lymphocyte proliferation.

The formation from simpler components of any compound containing pteridine (pyrazino(2,3-dipyrimidine)), e.g. pteroic acid, xanthopterin and folic acid.

Catalysis of the reaction: ATP + H2O + cation(out) = ADP + phosphate + cation(in).

The formation and repair of double strand breaks through a double Holliday junction intermediate that results in the equal exchange of genetic material between non-sister chromatids in a pair of homologous chromosomes. These reciprocal recombinant products ensure the proper segregation of homologous chromosomes during meiosis I and create genetic diversity.
