molecular function |
| GO:0003779 | | actin binding | | Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments. |
| GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| GO:0031014 | | troponin T binding | | Interacting selectively and non-covalently with troponin T, the tropomyosin-binding subunit of the troponin complex. |
biological process |
| GO:0060048 | | cardiac muscle contraction | | Muscle contraction of cardiac muscle tissue. |
| GO:0045893 | | positive regulation of transcription, DNA-templated | | Any process that activates or increases the frequency, rate or extent of cellular DNA-templated transcription. |
| GO:0003009 | | skeletal muscle contraction | | A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control. |
cellular component |
| 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. |
| GO:0005861 | | troponin complex | | A complex of accessory proteins (typically troponin T, troponin I and troponin C) found associated with actin in muscle thin filaments; involved in calcium regulation of muscle contraction. |
