Characterization of three cDNAs encoding two isozymes of an isoaspartyl protein carboxyl methyltransferase from human erythroid leukemia cells.

Abstract

Two different sizes (approximately 1.0 and 1.6 kb) of transcripts of an isoaspartyl protein carboxyl methyltransferase (PIMT) were detected in eight cell lines derived from human hemopoietic cells on Northern blot analysis. We found three different sizes of cDNAs (907, 1,553, and 1,600 bp) in human erythroid leukemia cells (HEL) and a unique cDNA sequence… (More)
