1.

regulation of atrial cardiac muscle cell action potential

Any process that modulates the frequency, rate or extent of action potential creation, propagation or termination in an atrial cardiac muscle cell contributing to the regulation of its contraction. This typically occurs via modulation of the activity or expression of voltage-gated...

Type
:
pathway
Taxonomic scope
:
conserved biosystem
BSID:
946567
GO
: GO:0098910
2.

gap junction channel activity involved in cardiac conduction electrical coupling

A wide pore channel activity that enables a direct cytoplasmic connection from one cardiomyocyte to an adjacent cardiomyocyte. The gap junction passes electrical signals between the cells contributing to cardiac conduction.

:
conserved biosystem
BSID:

GO
: GO:0086075
3.

cell communication by electrical coupling involved in cardiac conduction

The process that mediates signaling interactions between one cell and another cell by transfer of current between their adjacent cytoplasms via intercellular protein channels and contributes to the process of cardiac conduction.

5.

regulation of atrial cardiac muscle cell membrane depolarization

Any process that modulates the establishment or extent of a membrane potential in the depolarizing direction away from the resting potential in an atrial cardiomyocyte. Synonyms: atrial depolarization; electrocardiogram PR interval; regulation of atrial cardiac muscle cell depolarization;...

7.

gap junction hemi-channel activity

A wide pore channel activity that enables the transport of a solute across a membrane via a gap junction hemi-channel. Two gap junction hemi-channels coupled together form a complete gap junction. Synonym: connexon channel activity;

intercalated disc

A complex cell-cell junction at which myofibrils terminate in cardiomyocytes; mediates mechanical and electrochemical integration between individual cardiomyocytes. The intercalated disc contains regions of tight mechanical attachment (fasciae adherentes and desmosomes) and electrical...

10.

gap junction

A cell-cell junction that is composed of an array of small channels that permit small molecules to pass from one cell to another. At gap junctions, the membranes of two adjacent cells are separated by a uniform narrow gap of about 2-4 nm that is spanned by channel-forming proteins...

gap junction channel activity

A wide pore channel activity that enables a direct cytoplasmic connection from one cell to an adjacent cell. The gap junction can pass large solutes as well as electrical signals between cells. Gap junctions consist of two gap junction hemi-channels, or connexons, one contributed...
