After transiting to the nucleus SREBPs (SREBP1A/1C/2, SREBFs) bind short sequences, sterol regulatory elements (SREs), in the promoters of target genes (reviewed in Eberle et al. 2004, Weber et al. 2004). SREBPs alone are relatively weak activators of transcription, with SREBP1C being significantly weaker than SREBP1A or SREBP2. In combination with other transcription factors such as SP1 and NF-Y the SREBPs are much stronger activators. SREBP1C seems to more specifically target genes involved in fatty acid synthesis while SREBP2 seems to target genes involved in cholesterol synthesis (Pai et al. 1998).

MED1 is a component of each of the various Mediator complexes, that function as transcription co-activators. The MED1-containing compolexes include the DRIP, ARC, TRIP and CRSP compllexes.
Peroxisome proliferator receptor elements bind heterodimers containing a peroxisome proliferator receptor and a retinoic acid receptor. The consensus sequence is TGAMCTTTGNCCTAGWTYYG.
The SCD gene is transcribed to yield mRNA (Li et al. 1994) and the mRNA is translated to yield protein. The SREBP1A (SREBF1A) and SREBP1C (SREBF1C) transcription factors bind the promoter of the SCD gene and activate transcription in response to low cellular cholesterol (Tabor et al. 1999, Bee et al. 2001).
SREBP2 (SREBF2) binds and transactivates an unusual sterol regulatory element in the promoter of the TM7SF2 gene (Schiavoni et al. 2010). NF-Y binds the promoter and is important for activation by SREBP2. SREBP1A and SREBP1C can also bind the TM7SF2 promoter (Reed et al. 2008, Rome et al. 2008).
SREBP1A/1C/2 (SREBF1A/1C/2), together with NF-Y and SP1, bind and transactivate the promoter of the FDFT1 gene (Inoue et al. 1998, Pai et al. 1998, Reed et al. 2008, Rome et al. 2008). SREBP2 activates FDFT1 more strongly than does SREBP1A (Pai et al. 1998).
SREBP1A/1C/2 (SREBF1A/1C/2), together with NF-Y, bind and transactivate the promoter of the FDPS gene (Ericsson et al. 1996, Pai et al. 1998, Amemiya-Kudo et al. 2002, Reed et al. 2008, Rome et al. 2008, Ishimoto et al. 2010). The binding of NF-Y synergistically enhances the binding of SREBP1 (Ericsson et al. 1996). SREBP1A activates FDPS more strongly than does SREBP2 or SREBP1C (Amemiya-Kudo et al. 2002).
SREBP1A (SREBF1A) or SREBP1C, together with NF-Y and SP1, bind and transactivate the promoter of the FASN gene (Bennett et al. 1995, Pai et al. 1998, Xiong et al. 2000, Amemiya-Kudo et al. 2002, Shin et al. 2007, Choi et al. 2008, Rome et al. 2008). NF-Y is required for response to cholesterol (Xiong et al. 2000). SREBP1A activates FASN more strongly than does SREBP1C or SREBP2 (Pai et al. 1998, Amemiya-Kudo et al. 2002).
SREBP1A/1C/2 (SREBF1A/1C/2), together with NF-Y, bind and transactivate the promoter of the HMGCS1 gene (Maeda et al. 1998, Pai et al. 1998, Amemiya-Kudo et al. 2002, Reed et al. 2008). SREBP1A and SREBP2 activate HMGCS1 equally (Pai et al. 1998).
SREBP1A (SREBF1A) or SREBP2 binds and transactivates the promoter of the SQLE gene (Reed et al. 2008). The promoter also contains a consensus binding site for NF-Y (Nagai et al. 2002).
SREBP1A (SREBF1A) or SREBP2 binds and transactivates the promoter of the LSS gene (Pai et al. 1998, Rome et al. 2008). SREBP1A and SREBP2 activate LSS equally (Pai et al. 1998).
SREBP1A (SREBF1A) or SREBP1C bind and transactivate promoter II of the GPAM gene (Harada et al. 2012). Promoter II is active in lipogenic tissues. As inferred from mouse, NF-Y also binds the GPAM promoter with SREBP1A/1C.
SREBP1A (SREBF1A) or SREBP1C bind two sites in the promoter of the ACACA gene (Magana et al. 1997, Rome et al. 2008). Each site is required for activation of transcription.
SREBP1A (SREBF1A) or SREBP2, together with NF-Y, bind and transactivate the promoter of the HMGCR gene (Vallett et al. 1996, Pai et al. 1998, Reed et al. 2008, Rome et al. 2008). SREBP2 activates HMGCR slightly more than does SREBP1A (Pai et al. 1998). SREBP1A/2 binds 2 main sites and 2 auxiliary sites in the HMGCR promoter (Vallett et al. 1996).
SREBP1A (SREBF1A) or SREBP2, together with NF-Y and SP1, bind and transactivate the promoter of the CYP51A1 gene (Pai et al. 1998, Reed et al. 2008, Rome et al. 2008). SREBP1A and SREBP2 activate CYP51A1 equally (Pai et al. 1998).
SREBF1A (SREBP1A) and SREBF1C (SREBP1C) bind the promoter of the Stearoyl CoA Desaturase 1 (SCD1) gene and enhance transcription (Pai et al. 1998, Shimao et al. 1999, Tabor et al. 1999, Bene et al. 2001, reviewed in Horton et al. 2002).
