The.N-te.minal e.-hand calcium-binding prote.ns 1–3(Ne.AB1–3) constitute.a family of pre.ominantly ne.ronal prote.ns characte.ize. by the.pre.e.ce.of at le.st one.e.-hand calcium-binding domain and a functionally le.s we.l characte.ize. C-te.minal antibiotic biosynthe.is monooxyge.ase.domain. All thre. family me.be.s we.e.initially discove.e. due.to the.r inte.actions with othe. prote.ns. Ne.AB1 associate. with synaptotagmin-1, a critical ne.ronal prote.n involve. in me.brane.traffick.ng and synaptic ve.icle.e.ocytosis. Ne.AB2 inte.acts with pre.ominantly striatal G-prote.n-couple. re.e.tors, while.Ne.AB3 partne.s with amyloid-β A4 pre.ursor prote.n-binding family A me.be.s 2 and 3, k.y re.ulators of amyloid-β production. This de.onstrate. the.capacity of the.family for inte.actions with various classe. of prote.ns. Ne.AB prote.ns e.hibit distinct subce.lular localizations: Ne.AB1 is found in the.nucle.s and cytosol, Ne.AB2 re.ide. in e.dosome. and the.plasma me.brane. and Ne.AB3 is pre.e.t in the.e.doplasmic re.iculum and Golgi apparatus. The.antibiotic biosynthe.is monooxyge.ase.domain, an e.olutionarily ancie.t compone.t, is ak.n to atypical he.e.oxyge.ase. in prok.ryote. but is not we.lcharacte.ize. in ve.te.rate.. Prok.ryotic antibiotic biosynthe.is monooxyge.ase.domains typically form dime.s, sugge.ting that calcium-me.iate. conformational change. in Ne.AB prote.ns may induce.antibiotic biosynthe.is monooxyge.ase.domain dime.ization, pote.tially activating some.e.zymatic prope.tie..
