The human PGM-2 and its chromosomal localization in man-mouse hybrids
Human Genetics
|July 26, 1977
Summary
Researchers developed a rapid method to detect phosphoglucomutase-2 (PGM-2) in human cells. This genetic analysis strongly suggests the human PGM-2 gene is located on chromosome 4.
Area of Science:
- Human genetics
- Biochemistry
- Cell biology
Background:
- Phosphoglucomutase-2 (PGM-2) is an enzyme found in human tissues.
- Understanding enzyme locus assignment is crucial for genetic mapping and disease research.
Purpose of the Study:
- To establish a rapid detection method for phosphoglucomutase-2 (PGM-2).
- To determine the chromosomal location of the human PGM-2 gene.
Main Methods:
- Electrophoresis of human red blood cell and tissue extracts on Cellogel.
- Analysis of primate-rodent somatic cell hybrids for PGM-2 presence and human chromosome content.
Main Results:
- A single locus for phosphopentomutase (PGM-2) was identified in humans.
- Data from 20 man-mouse somatic cell hybrid clones favored the assignment of the human PGM-2 locus to chromosome 4.
Conclusions:
- The developed method allows for rapid PGM-2 detection.
- The human PGM-2 gene is provisionally assigned to chromosome 4, advancing human gene mapping efforts.
