The regionalization process that results in the determination of the identity of part of an organism or organ where those parts are of the type that occur in the ventral region. Identity is considered to be the aggregate of characteristics by which a structure is recognized.

The chemical reactions and pathways resulting in the formation of 5,6,7,8-tetrahydromethanopterin.

The chemical reactions and pathways resulting in the formation of a tetrahydromethanopterin.

Enables the transfer of a solute or solutes from one side of a membrane to the other according to the reaction: ATP + H2O + doxorubicin(in) = ADP + phosphate + doxorubicin(out).

OBSOLETE. Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter to protect the cell or organism in response to the presence of a fungus.

The movement of a B cell receptor (BCR) from the plasma membrane to the inside of the cell, which results in positive regulation of toll-like receptor 9 (TLR9) signaling. For example, internalized BCR signals to recruit TLR9 from multiple small endosomes to large autophagosome-like compartments to enhance TLR9 signaling.

A receptor-mediated endocytosis process that results in the movement of a B cell receptor from the plasma membrane to the inside of the cell.

Any process in which the internalization of a signaling receptor activates or increases the frequency, rate or extent of signal transduction. Receptor internalization can enhance signaling by concentrating signaling molecules in one location, or by moving a ligand-activated receptor to the location of downstream signaling proteins. Endosomes for example can serve as important intracellular signaling platforms.

Any process that modulates the frequency, rate or extent of lung ciliated cell differentiation.

Any process that modulates the frequency, rate or extent of epithelial cell differentiation.

Any process that stops, prevents or reduces the frequency, rate or extent of lung ciliated cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of epithelial cell differentiation.

Any process that activates or increases the frequency, rate or extent of lung ciliated cell differentiation.

Any process that modulates the frequency, rate or extent of lung goblet cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of isotype switching to IgE isotypes.

Any process that modulates the frequency, rate or extent of isotype switching to IgE isotypes.

Any process that activates or increases the frequency, rate or extent of isotype switching to IgE isotypes.

The switching of activated B cells from IgM biosynthesis to IgD biosynthesis, accomplished through a recombination process involving an intrachromosomal deletion between switch regions that reside 5' of the IgM and IgD constant region gene segments in the immunoglobulin heavy chain locus.

The switching of activated B cells from IgM biosynthesis to biosynthesis of other isotypes of immunoglobulin, accomplished through a recombination process involving an intrachromosomal deletion involving switch regions that reside 5' of each constant region gene segment in the immunoglobulin heavy chain locus.
