Interacting selectively with the SNAP receptor syntaxin-1.

Binds to and modulates the activity of the molecular chaperone Hsc70.

A fine cytoplasmic channel, found in all higher plants, that connects the cytoplasm of one cell to that of an adjacent cell.

A chlorophyll-containing plastid with thylakoids organized into grana and frets, or stroma thylakoids, and embedded in a stroma.

myosin phosphatase, intrinsic regulator activity

Modulation of the activity of the enzyme myosin phosphatase.

Interacting selectively with myosin, any of a superfamily of molecular motor proteins that bind to actin and use the energy of ATP hydrolysis to generate force and movement along actin filaments.

An enzyme complex that catalyzes the removal of the phosphate group from phosphomyosin.

Interacting selectively with a class I myosin; myosin I heavy chains are single-headed, possess tails of various lengths, and do not self-associate into bipolar filaments.

Interacting selectively with TATA-binding protein (TBP), a component of various transcription factors.

Catalysis of the cleavage of the C-terminal propeptide at Ala-Asp in type I and II procollagens and at Arg-Asp in type III.

The addition of a nitrosyl group to a protein amino acid.

regulation of transforming growth factor beta receptor signaling pathway

regulation of transforming growth factor beta receptor signalling pathway

Any process that modulates the frequency, rate or extent of activity of any TGFbeta receptor signaling pathway.

Interacting selectively with any member of the Ras superfamily of monomeric GTPases.

Catalysis of the reaction: ATP + a protein = ADP + a phosphoprotein; activity is dependent on the binding of a regulatory cyclin subunit and full activity requires stimulatory phosphorylation by a CDK-activating kinase (CAK).

myosin phosphatase, intrinsic catalyst activity

Catalysis of the reaction: a phosphoprotein + H2O = a protein + phosphate.

Catalysis of the reaction: N-acylsphingosine + H2O = a fatty acid + sphingosine.

Catalysis of the reaction: glycosyl-N-acylsphingosine + H2O = a sugar + N-acylsphingosine.
