ApoA-II modulates the association of HDL with class B scavenger receptors SR-BI and CD36
Journal of Lipid Research, 2004 The class B scavenger receptors SR-BI and CD36 exhibit a broad ligand binding specificity. SR-BI is well characterized as a HDL receptor that mediates selective cholesteryl ester uptake from HDL.

Steroid Receptors and Vertebrate Evolution [PDF]
arXiv, 2019 Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

Accuracy of direct gradient sensing by cell-surface receptors [PDF]
arXiv, 2009 Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.
