protein import into nucleus obsolete sterol regulatory element binding protein import into nucleus true GO:0035105 SREBP import into nucleus involved in sterol depletion response SREBP import into nucleus sterol regulatory element binding protein nuclear translocation SREBP nuclear translocation sterol depletion response, SREBP import into nucleus OBSOLETE. The transfer of a sterol regulatory element binding protein (SREBP) into the nucleus, across the nuclear membrane, in response to altered levels of one or more lipids. SREBPs are transcription factors that bind sterol regulatory elements (SREs), DNA motifs found in the promoters of target genes. sterol depletion response, sterol regulatory element binding protein import into nucleus sterol depletion response, SREBP nuclear translocation GO:0006993 The reason for obsoletion is that all proteins are imported into the nucleus via the same mechanism, so the import of individual proteins should be captured with extensions or by GO-CAM models. sterol regulatory element binding protein nuclear translocation involved in sterol depletion response sterol regulatory element binding protein import into nucleus involved in sterol depletion response biological_process sterol depletion response, sterol regulatory element binding protein nuclear translocation regulation of protein import into nucleus
