Narrative:

Landed on 12R instructed to cross 12L at F. Ground ATC instructed; taxi Z to the gate. Upon crossing 12L I turned the wrong direction; stopped and had the first officer call for new taxi instructions. Told ATC we made a wrong turn. ATC gave new instructions to taxi Z; east; D; Y to the gate. Upon completing the turn on yankee; ground gave us a number to call. I complied once at the gate. The supervisor asked if I saw the NOTAM that taxiway between D and east on zulu was closed. I said yes; however; was following ground ATC new taxi instructions. Since I received this clearance and there were no markers or lights indicating the taxiway was closed; I assumed it was now open. The ATIS with the NOTAM was 35 minutes old. The supervisor said; 'actually it is open for towed aircraft; but we don't like to advertise it.'in any event; if my aircraft did not belong on that 'closed' taxiway; ATC should have never given me a clearance to taxi on it and there should have been some type of markings/lights indicating it was closed; especially at night.I made a wrong turn off the runway; should have studied the gates and referenced the taxiways. And when ATC's instructions where contrary to ATIS; NOTAM; we should have inquired.in any event; if my aircraft did not belong on that 'closed' taxiway; ATC should have never given me a clearance to taxi on it and there should have been some type of markings/lights indicating it was closed; especially at night.
