Enables the transfer of D-galactonate, the D-enantiomer of galactonate, from one side of a membrane to the other.

The developmental process pertaining to the initial formation of an endocardial cushion. The endocardial cushion is a specialized region of mesenchymal cells that will give rise to the heart septa and valves.

Enables the transfer of D-glucuronate, the D-enantiomer of glucuronate, from one side of a membrane to the other.

The series of molecular signals generated as a consequence of activation of the transmembrane protein Smoothened contributing to the modulation of the frequency, rate or extent of cardioblast proliferation in the secondary heart field. 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.

The series of molecular signals initiated by binding of an extracellular ligand to a Notch receptor on the surface of the target cell contributing to the modulation of the frequency, rate or extent of cardioblast proliferation in the secondary heart field. 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 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 detecting the defenses of a symbiont organism. The symbiont is defined as the smaller of the organisms involved in a symbiotic interaction.

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 detecting the defenses of another organism.

OBSOLETE. The process in which an organism effects a change in the structure or function of a second organism, mediated by a substance secreted by a type III secretion system in the first organism, where the two organisms are in a symbiotic interaction.

OBSOLETE. The process in which an organism effects a change in the structure or function of a second organism, mediated by a substance secreted by a type II secretion system in the first organism, where the two organisms are in a symbiotic interaction.

OBSOLETE. An interaction with a second organism mediated by a substance secreted by the first organism by a type IV secretion system, where the two organisms are in a symbiotic interaction.

OBSOLETE. The process in which an organism effects a change in the structure or function of a second organism, mediated by a substance secreted by a type IV secretion system in the first organism, where the two organisms are in a symbiotic interaction.

The series of molecular signals initiated by the binding of a member of the BMP (bone morphogenetic protein) family to a receptor on the surface of a target cell, which contributes to the modulation of the frequency, rate or extent of cardioblast proliferation in the secondary heart field. 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.

OBSOLETE. The process in which an organism effects a change in enzyme activity in a second organism, where the two organisms are in a symbiotic interaction.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands contributing to the modulation of the frequency, rate or extent of cardioblast proliferation in the secondary heart field. 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.

OBSOLETE. Any process in which an organism stops, prevents, or reduces the frequency, rate or extent of the deposition of callose by the host in its cell walls, occurring as part of the defense response of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

A canonical Wnt signaling pathway that contributes to an increase in the frequency, or rate of cardioblast proliferation in the secondary heart field. 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.

OBSOLETE. The process in which an organism effects a change in the function of proteins in a second organism, where the two organisms are in a symbiotic interaction.

OBSOLETE. Any process in which an organism stops, prevents, or reduces the frequency, rate or extent of the functional activity of proteins in a second organism, where the two organisms are in a symbiotic interaction.

Any process that modulates the frequency, rate or extent of cardioblast proliferation in the primary heart field. 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. In mammals the primary heart field gives rise to the left ventricle.

The multiplication or reproduction of cardioblasts, resulting in the expansion of the population in the heart field. 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.
