abstractText | We showed previously that the alternative splicing of chondroitin sulfate attachment domains (CS alpha and CS beta) yielded multiforms of the PG-M core protein in mouse. A transcript encoding a new short form of the core protein PG-M(V3) was found in various mouse tissues using polymerase chain reaction. DNA sequences of the polymerase chain reaction products suggested that PG-M(V3) had no chondroitin sulfate attachment domain. PG-M(V3) was also detected in various human tissues. The presence of a transcript for PG-M(V3) was further supported by Northern blot analysis. Southern blot analysis confirmed that multiforms of the PG-M core protein, including PG-M(V3), were derived from a single genomic locus by an alternative splicing mechanism. Because PG-M(V3) has no chondroitin sulfate attachment region, which is the most distinctive portion of a proteoglycan molecule, this form may have a unique function. |
