Combining with transforming growth factor beta to initiate a change in cell activity; facilitates ligand binding to type I and type II TGF-beta receptors.

Enables the directed movement of electrons within the noncyclic electron transport pathway of photosynthesis.

The process preceding formation of the peptide bond between the first two amino acids of a protein in a mitochondrion. This includes the formation of a complex of the ribosome, mRNA, and an initiation complex that contains the first aminoacyl-tRNA.

Enables the directed movement of electrons within the cytochrome b6/f complex of photosystem II.

The successive addition of amino acid residues to a nascent polypeptide chain during protein biosynthesis in a mitochondrion.

Binding to a class II myosin, any member of the class of 'conventional' double-headed myosins that includes muscle myosin.

The process resulting in the release of a polypeptide chain from the ribosome in a mitochondrion, usually in response to a termination codon (note that mitochondria use variants of the universal genetic code that differ between different taxa).

The synthesis of aminoacyl tRNA by the formation of an ester bond between the 3'-hydroxyl group of the most 3' adenosine of the tRNA, to be used in ribosome-mediated polypeptide synthesis in a mitochondrion.

Any process that modulates the frequency, rate or extent of mitochondrial gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product (protein or RNA).

The chemical reactions and pathways resulting in the breakdown of acetoin, 3-hydroxy-2-butanone.

The chemical reactions and pathways resulting in the formation of acetoin, 3-hydroxy-2-butanone.

Binding to an antisigma factor, a factor which inhibits the ability of the sigma factor to function as a transcriptional initiator.

Any process that modulates the frequency, rate or extent of cell proliferation resulting in the maintenance of a steady-state number of cells within a tissue.

Any process that modulates the occurrence or rate of cell death by apoptosis that results in the maintenance of the steady-state number of cells within a tissue.

Any process that modulates the frequency, rate or extent of mesenchymal cell proliferation that contributes to the progression of the prostate gland over time. A mesenchymal cell is a cell that normally gives rise to other cells that are organized as three-dimensional masses, rather than sheets.

The series of molecular signals generated as a consequence of activation of the transmembrane Smoothened-type protein in the mesenchymal cells of the prostate that contribute to the progression of the prostate over time. This process contributes to lung development.

The developmental process in which an ectodermal placode forms. An ectodermal placode is a thickening of the ectoderm that is the primordium of many structures derived from the ectoderm.

The developmental process in which a hair placode forms. An hair follicle placode is a thickening of the ectoderm that will give rise to the hair follicle bud.
