Septin-like protein involved in the correct orientation of forespore membrane extension during sporulation. Component of the sporulation-specific septin complex composed of at least spn2, spn5, spn6 and spn7. The sporulation-specific septin complex associates to the forespore membrane and forms partial or complete ring-like structures that curl around each haploid nucleus. Expressed during meiosis. Expression is under the control of the meiosis-specific transcription factor mei4. Belongs to the TRAFAC class TrmE-Era-EngA-EngB-Septin-like GTPase superfamily. Septin GTPase family.
