calcium ion transmembrane transporter activity

Enables the transfer of calcium (Ca) ions from one side of a membrane to the other.

ommatidial rotation

The process in which photoreceptors are arranged in ommatidia in the dorsal and ventral fields to be mirror images. The polarity is established in the imaginal discs concurrently with cell fate specification.

brush border assembly

The aggregation, arrangement and bonding together of adjacent microvilli through the formation of Ca(2+)-dependent adhesion links between them, forming a brush border.

adenylate cyclase-activating adrenergic receptor signaling pathway involved in cardiac muscle relaxation

An adrenergic receptor signaling pathway that contributes to a reduction in cardiac muscle contraction. Beta-adrenergic receptor-induced cardiac relaxation is achieved by a GPCR-activated adenylate cyclase generating cAMP; cAMP then activates the cAMP-dependent protein kinase A (PKA), which phosphorylates the sarcoplasmic reticulum (SR) membrane protein PLB. In its non-phosphorylated state, PLB acts as an inhibitor of the ATPase Ca(2+) pump of the cardiac SR (SERCA2a); inhibition of the pump is relieved upon phosphorylation. The pump removes Ca(2+) from the cytoplasm, thereby preventing cytosolic Ca(2+)-dependent activation of contractile proteins, leading to enhanced muscle relaxation.

intermicrovillar adhesion

The cell-cell adhesion process by which adjacent microvilli attach to each other through Ca(2+)-dependent adhesion links made of protocadherin-24 and mucin-like protocadherin.

calcium ion transport

The directed movement of calcium (Ca) ions into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.

obsolete calcium incorporation into metallo-oxygen cluster via bis-L-aspartato tris-L-glutamato L-histidino calcium tetramanganese tetroxide

OBSOLETE. The incorporation of calcium into a 4Mn-Ca-4O complex by bis-L-aspartato tris-L-glutamato L-histidino calcium tetramanganese tetroxide as in the photosystem II catalytic site.

obsolete manganese incorporation into metallo-oxygen cluster via bis-L-aspartato tris-L-glutamato L-histidino calcium tetramanganese tetroxide

OBSOLETE. The incorporation of manganese into a 4Mn-Ca-4O complex by bis-L-aspartato tris-L-glutamato L-histidino calcium tetramanganese tetroxide as in the photosystem II catalytic site.

subthalamus development

The process whose specific outcome is the progression of the subthalamus over time, from its formation to the mature structure. The subthalamus is the anterior part of the diencephalon that lies between the thalamus, hypothalamus, and tegmentum of the mesencephalon, including subthalamic nucleus, zona incerta, the fields of Forel, and the nucleus of ansa lenticularis.

magnetoreception by sensory perception of chemical stimulus

The series of events required for an organism to receive a chemical stimulus relating to a magnetic field, convert it to a molecular signal, and recognize and characterize the signal. It is believed that organisms such as birds and salamanders use a 'chemical compass': chemical reactions that involve transitions between different spin states can be influenced by magnetic fields and by detecting the different product ratios, these organisms can perceive the direction of the magnetic field. The mechanism by which this is detected is not certain but it may also involve light stimuli.
