molecular function |
| GO:0005516 | | calmodulin binding | | Interacting selectively and non-covalently with calmodulin, a calcium-binding protein with many roles, both in the calcium-bound and calcium-free states. |
| GO:0017020 | | myosin phosphatase regulator activity | | Modulation of the activity of the enzyme myosin phosphatase. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0008157 | | protein phosphatase 1 binding | | Interacting selectively and non-covalently with the enzyme protein phosphatase 1. |
| GO:0004864 | | protein phosphatase inhibitor activity | | Stops, prevents or reduces the activity of a protein phosphatase, an enzyme that hydrolyzes phosphate groups from phosphorylated proteins. |
biological process |
| GO:0048644 | | muscle organ morphogenesis | | The process in which the anatomical structures of muscle are generated and organized. |
| GO:0043086 | | negative regulation of catalytic activity | | Any process that stops or reduces the activity of an enzyme. |
| GO:0045892 | | negative regulation of transcription, DNA-templated | | Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0018105 | | peptidyl-serine phosphorylation | | The phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine. |
| GO:0045907 | | positive regulation of vasoconstriction | | Any process that activates or increases the frequency, rate or extent of vasoconstriction. |
| GO:0050790 | | regulation of catalytic activity | | Any process that modulates the activity of an enzyme. |
| GO:0014823 | | response to activity | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an activity stimulus. |
| GO:0042493 | | response to drug | | Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease. |
cellular component |
| GO:0031674 | | I band | | A region of a sarcomere that appears as a light band on each side of the Z disc, comprising a region of the sarcomere where thin (actin) filaments are not overlapped by thick (myosin) filaments; contains actin, troponin, and tropomyosin; each sarcomere includes half of an I band at each end. |
| GO:0031430 | | M band | | The midline of aligned thick filaments in a sarcomere; location of specific proteins that link thick filaments. Depending on muscle type the M band consists of different numbers of M lines. |
| GO:0043292 | | contractile fiber | | Fibers, composed of actin, myosin, and associated proteins, found in cells of smooth or striated muscle. |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0005634 | | nucleus | | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. |
