SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,organelle,membrane
	intracellular,cytoplasm,organelle,endoplasmic reticulum
	intracellular,cytoplasm,organelle,Golgi
	intracellular,cytoplasm,cytosolic,vesicle
text	predominantely detected in the cytoplasm in vesicle-like patterns but not at the plasma membrane (Lai 2009)
	localizing to Golgi and endoplasmic reticulum membranes

basic FUNCTION	contribute to the electrical and metabolic coupling, or to signaling between retinal neurons via the secondary messengers (Dvoriantchikova 2006)
	like connexins, may play an important role in hearing (Wang 2009)
	PANX2 protein expression plays a role in regulating the timing of neuronal differentiation

CELLULAR PROCESS

PATHWAY

metabolism

a component

INTERACTION

DNA

RNA

small molecule

protein	strongly interacts with the core and high-mannose species of PANX1 but not with PANX3 (Penuela 2009)
	physically interacts with PANX1 to reduce current amplitude

cell & other

REGULATION

Other	regulated by glycosylation (regulates pannexin intermixing and cellular localization) (Penuela 2009)
	endogenous post-translational regulation, specific to early neural progenitor cells
