expression vector
Restriction digests of the clone give the following sizes (kb): BglII--8.5; EcoRI--7.3, 1.2; HindIII--5.6, 1.8, 1.1.
The fission yeast tagging vectors, pSLF172 (ATCC 87609), pSLF272 (ATCC 87610) and pSLF372 (ATCC 87611), contain three versions of the nmt1 promoter: full strength (nmt1), medium strength (nmt1*) and low strength (nmt1**), respectively.
The weaker promoters (nmt1* and nmt1**) contain mutations that attenuate both repressed and induced levels of expression.
Each version of the nmt1 promoter can be expressed at low or high levels in thiamine-free media.
The vector was designed to tag expressed protein at N-terminus with triple HA tag, which contains an internal BamHI site. The vector lack a stop codon.
The vector was constructed by cutting pSLF173 with SacI and XhoI, isolating the fragment containing the HA polylinker, and ligating into XhoI-SacI digested REP42X.
