positive regulation of protein secretion

Any process that activates or increases the rate, frequency or extent of the regulated release of a protein from a cell or group of cells.

The assembly and arrangement of PML bodies, a class of nuclear body; they react against SP100 auto-antibodies (PML = promyelocytic leukemia).

positive regulation of cytokine secretion

Any process that activates or increases the rate, frequency or extent of the regulated release of cytokines from a cell or group of cells.

purinergic nucleotide receptor activity, G-protein coupled

purinergic nucleotide receptor activity, G protein coupled

The breakdown into simpler components of SMAD signaling proteins by ubiquitination and targeting to the proteasome.

positive regulation of interleukin-1 secretion

Any process that activates or increases the rate, frequency or extent of the regulated release of interleukin-1 from a cell or group of cells.

positive regulation of interleukin-1 beta secretion

Any process that activates or increases the rate, frequency or extent of the regulated release of interleukin-1 beta from a cell or group of cells.

Any series of molecular signals generated as a consequence of an estrogen binding to its receptor.

The initial step in the formation of an actin filament, in which actin monomers combine to form a new filament. Nucleation is slow relative to the subsequent addition of more monomers to extend the filament.

Any series of molecular signals generated as a consequence of an androgen binding to its receptor.

The assembly of the long bundles of actin filaments known as actin cables.

Any series of molecular signals initiated by a ligand entering the target cell, where it binds to an intracellular receptor.

Catalysis of the reaction: diacylglycerol pyrophosphate + H20 = 3-sn-phosphatidate + phosphate.

major histocompatibility complex class II receptor

A major histocompatibility complex class II receptor. These display processed antigens from virally-infected or transformed cells. Class-II-positive cells ('antigen-presenting cells') can take up antigens from outside by endocytosis, degrade them into small peptides, and re-export the peptides (now bound to MHC class II protein) to the cell surface. These peptide-MHC class II complexes can then be recognized by specific CD4+ lymphocytes.
