Title: Göran Hjälm: Innovator in Calcium Sensor Protein Research

Introduction

Göran Hjälm is a notable inventor based in Uppsala, Sweden. He has made significant contributions to the field of molecular biology, particularly in the study of calcium sensor proteins. With a total of 2 patents, his work has implications for understanding calcium regulation in various organ systems.

Latest Patents

Hjälm's latest patents focus on nucleic acids encoding human calcium sensor proteins. The first patent details the isolation of a cDNA clone that encodes the calcium sensor found in human placenta. Subsequent Northern blots confirm mRNA expression in human parathyroid and kidney tubule cells. The research demonstrates close sequence similarity with the rat Heymann nephritis antigen, a glycoprotein known for its calcium binding ability. Immunohistochemistry supports a tissue distribution of the calcium sensor protein that aligns with previous descriptions of the Heymann antigen. Hjälm proposes that this calcium sensor protein serves as a universal sensor for detecting variations in extracellular calcium, playing a crucial role in calcium regulation across different organ systems. The protein belongs to the LDL-superfamily of glycoproteins, which are primarily recognized for their function as protein receptors, while also possessing important calcium binding capabilities.
