It may function as an integral membrane protein involved in cell-cell/matrix interactions, and may modulate intracellular calcium homoeostasis and other signal-transduction pathways.
Close correlations between agents demonstrates biological and pharmacological importance and implies a common intracellular target despite dissimilarity in structure.
Most animal cells and single-celled organisms have very little color, and their intracellular organelles are almost totally invisible under simple bright field illumination.
