Are lobster fibrinogen and cold-insoluble globulin related molecules?
Abstract:
Several of the molecular properties of lobster fibrinogen and CIg have been compared. There are some significant similarities between these two proteins; however, to date, no direct experiments have demonstrated molecular homologies. Studies involving cyanogen bromide mapping, additional immunologic probing, and modifications of cell morphology effected by lobster fibrinogen are currently in progress. It is anticipated that these and other experimental approaches will provide direct evidence to answer the question, posed by the title of this paper.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
