We have examined the expression of the c-src gene product in a variety of embryonic and adult tissues, in peripheral blood cells, and in cells transformed by other tumor viruses, in an attempt to identify the types of cells in which pp60c-src might provide a specific function. These studies have indicated that c-src gene expression is regulated at multiple levels in different cell types and have suggested that pp60c-src is not exclusively involved in the regulation of cell proliferation. The lowest levels of pp60c-src were found in fibroblasts, which have previously served as the standard cell type for comparisons between pp60c-src and pp60v-src. The highest levels of pp60c-src-specific kinase activity were detected in three types of cells: neurons, platelets, and polyoma virus transformed cells. In this report, we will compare the expression of pp60c-src in fibroblasts to that in platelets, neurons, and polyoma virus transformed fibroblasts. In each of the three latter cell types, the c-src gene product displays a unique pattern of expression which can be distinguished from that in fibroblasts (see diagram Fig. 1).

UI	MeSH Term	Description	Entries
D005786	Gene Expression Regulation	Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control (induction or repression) of gene action at the level of transcription or translation.	Gene Action Regulation,Regulation of Gene Expression,Expression Regulation, Gene,Regulation, Gene Action,Regulation, Gene Expression
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D012191	Retroviridae Proteins	Proteins from the family Retroviridae. The most frequently encountered member of this family is the Rous sarcoma virus protein.	Leukovirus Proteins,Retrovirus Proteins,Proteins, Leukovirus,Proteins, Retroviridae,Proteins, Retrovirus
D014407	Tumor Cells, Cultured	Cells grown in vitro from neoplastic tissue. If they can be established as a TUMOR CELL LINE, they can be propagated in cell culture indefinitely.

D015688	Oncogene Protein pp60(v-src)	A tyrosine-specific protein kinase encoded by the v-src oncogene of ROUS SARCOMA VIRUS. The transforming activity of pp60(v-src) depends on both the lack of a critical carboxy-terminal tyrosine phosphorylation site at position 527, and the attachment of pp60(v-src) to the plasma membrane which is accomplished by myristylation of its N-terminal glycine.
