The insert contains the following restriction sites (approximate kb from the 5' end): SacI--0.4 (intron 1); BglII--1.0 (intron 3); PstI--1.1, 3.0 (exon 4, 3' flanking); BamHI--1.9 (exon 5); SalI--2.6 (3' flanking).
Restriction digests of the clone give the following sizes (kb): EcoRI--3.9, 3.4; BamHI--4.1, 3.1; PstI--3.8, 1.8 (doublet).
The insert detects a mRNA of 2.2 kb.
