Any process that activates or increases the frequency, rate or extent of lymphocyte activation.

The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the T cell receptor to augment T cell activation.

A calcium-transporting P-type ATPase activity involved in regulation of postsynaptic cytosolic calcium ion concentration.

The process of providing, via surface-bound receptor-ligand pairs, a second, antigen-independent, signal in addition to that provided by the B cell receptor to augment B cell activation.

A protein complex conserved in eukaryotes and associated with the replication fork; the complex stabilizes stalled replication forks and is thought to be involved in coordinating leading- and lagging-strand synthesis and in replication checkpoint signaling.

Catalysis of the reaction: pyruvate + taurine = L-alanine + sulfoacetaldehyde.

The process in which the migration of an axon growth cone of a retinal ganglion cell (RGC) is directed to its target in the brain in response to a combination of attractive and repulsive cues.

The series of molecular signals within the cell that are mediated by a member of the Ran family of proteins switching to a GTP-bound active state.

The series of molecular signals within the cell that are mediated by a member of the Ras superfamily of proteins switching to a GTP-bound active state.

The proteolytic cleavage of a transmembrane protein leading to the release of an intracellular domain.

A RNA polymerase I-specific transcription factor complex that is required for the transcription of rDNA by RNA polymerase I. In yeast the complex consists of Rrn6p, Rrn7p, and Rrn11p.

Any process that modulates the frequency, rate or extent of the directed movement of proteins from the endoplasmic reticulum.

Any process that modulates the frequency, rate or extent of the directed movement of proteins within cells.

Any calcium:cation antiporter activity that is involved in regulation of postsynaptic cytosolic calcium ion concentration.

Any process that stops, prevents, or reduces the frequency, rate or extent of the directed movement of proteins from the endoplasmic reticulum.

Any process that decreases the frequency, rate or extent of the directed movement of proteins within cells.

Any process that stops, prevents or reduces the frequency, rate or extent of cardioblast proliferation.

Any process that modulates the frequency, rate or extent of cardioblast proliferation. A cardioblast is a cardiac precursor cell. It is a cell that has been committed to a cardiac fate, but will undergo more cell division rather than terminally differentiating.

Any process that activates or increases the frequency, rate or extent of directed movement of proteins from the endoplasmic reticulum.
