背景信息

Anoctamin 2 (ANO2), also known as transmembrane protein 16B (TMEM16B), is a calcium-activated chloride channel (CaCC) belonging to the anoctamin family, which comprises ten members (ANO1-10) in vertebrates. Discovered in 2008. ANO2 shares structural homology with ANO1. including eight transmembrane domains and conserved calcium-binding motifs. Unlike ANO1. which is broadly expressed in epithelial and smooth muscle tissues, ANO2 is predominantly found in the nervous system, retina, and olfactory epithelium, playing critical roles in sensory transduction and neuronal excitability.

In the central nervous system, ANO2 regulates synaptic transmission by modulating chloride flux, influencing action potential duration and neurotransmitter release. In olfactory sensory neurons, it amplifies odorant signals by mediating chloride efflux, while in the retina, it contributes to phototransduction and light adaptation. Dysregulation of ANO2 has been implicated in neurological disorders, including epilepsy and schizophrenia, as well as retinal degeneration.

Recombinant ANO2 protein is engineered for in vitro studies to dissect its biophysical properties, ion selectivity, and calcium sensitivity. Produced via heterologous expression systems (e.g., HEK293 or CHO cells), the purified protein enables structural analyses (e.g., cryo-EM) and drug screening for channel modulators. Its study also aids in understanding pathologies linked to ANO2 mutations, such as congenital stationary night blindness and glioblastoma progression. Research on ANO2 recombinant protein thus bridges molecular mechanisms to therapeutic targeting in neurophysiological and sensory diseases.
