"The serum response element (SRE), a region of the c-fos gene which controls growth factor-induced transcription, is [...] shown to mediate c-fos transcription in response to activation of L-type voltage-sensitive calcium channels. Calcium-dependent transcriptional activation through the SRE is mediated by the serum response factor (SRF). Membrane depolarization induces phosphorylation of SRF at Ser-103, an event shown to enhance the ability of SRF to bind the SRE."[1]

The SRE wild type (SREwt) contains the nucleotide sequence ACAGGATGTCCATATTAGGACATCTGC, of which CCATATTAGG is the CArG box, TTAGGACAT is the C/EBP box, and CATCTG is the E box.[1]

Human genes

Gene ID: 2353 is FOS Fos proto-oncogene, AP-1 transcription factor subunit. "The Fos gene family consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation. In some cases, expression of the FOS gene has also been associated with apoptotic cell death."[2] "Serum response factor and the (CC(A/T)6GG) (CArG) box interact to promote the transcription of c-fos and muscle genes".[3]
