Catalysis of the cleavage of a flap structure in DNA, but not other DNA structures; processes the ends of Okazaki fragments in lagging strand DNA synthesis.

regulation of receptor mediated endocytosis

Any process that modulates the frequency, rate or extent of receptor mediated endocytosis, the uptake of external materials by cells, utilizing receptors to ensure specificity of transport.

The joining of the lipid bilayer membrane around a vesicle to the lipid bilayer membrane around the Golgi.

The creation of a single organelle from two or more organelles.

The creation of two or more organelles by division of one organelle.

The process whose specific outcome is the progression of the alveolus over time, from its formation to the mature structure. The alveolus is a sac for holding air in the lungs; formed by the terminal dilation of air passageways.

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

The chemical reactions involving proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.

The formation from simpler components of proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.

The breakdown into simpler components of proline (pyrrolidine-2-carboxylic acid), a chiral, cyclic, nonessential alpha-amino acid found in peptide linkage in proteins.

The chemical reactions involving L-serine, the levorotatory isomer of 2-amino-3-hydroxypropanoic acid.

The formation from simpler components of L-serine, the levorotatory isomer of 2-amino-3-hydroxypropanoic acid.

mitogen-activated protein kinase p38 binding

Interacting selectively with mitogen-activated protein kinase p38, an enzyme that catalyses the transfer of phosphate from ATP to hydroxyl side chains on proteins in response to mitogen activation.
