Malignant osteopetrosis: c-src kinase is not reduced in fibroblasts. 1993

Targeted disruption of the c-src gene leads to a severe form of osteopetrosis in mice [2]. As the c-src gene is expressed in all tissues and cells tested, we have analyzed fibroblasts from three individuals with malignant, congenital osteopetrosis for the expression of c-src at the protein level. No differences could be detected in c-src protein and c-src kinase activity levels between fibroblasts from healthy controls and affected individuals. Thus, impairment of c-src function as an etiological factor in human osteopetrosis appears unlikely in the individuals investigated.

D016392	Proto-Oncogene Proteins pp60(c-src)	Membrane-associated tyrosine-specific kinases encoded by the c-src genes. They have an important role in cellular growth control. Truncation of carboxy-terminal residues in pp60(c-src) leads to PP60(V-SRC) which has the ability to transform cells. This kinase pp60 c-src should not be confused with csk, also known as c-src kinase.	c-src Protein pp60,pp60(c-src),src Proto-Oncogene Protein pp60,Phosphoprotein pp60(c-src),Proto-Oncogene Protein pp60(c-src),Proto-Oncogene Protein src,pp60 c-src,src Proto-Oncogene Product,Protein pp60, c-src,Protein src, Proto-Oncogene,Proto Oncogene Protein src,Proto-Oncogene Product, src,c src Protein pp60,c-src, pp60,pp60 c src,pp60, c-src Protein,src Proto Oncogene Product,src Proto Oncogene Protein pp60
D019061	src-Family Kinases	A PROTEIN-TYROSINE KINASE family that was originally identified by homology to the Rous sarcoma virus ONCOGENE PROTEIN PP60(V-SRC). They interact with a variety of cell-surface receptors and participate in intracellular signal transduction pathways. Oncogenic forms of src-family kinases can occur through altered regulation or expression of the endogenous protein and by virally encoded src (v-src) genes.
