Table 1. Data bank (InterProScan, Motif Scan in a Protein Sequence and ExPASy) analysis of the proteins present in the complex formed over BP.

Spot number Accesion number Name Description pI Molecular mass (Da)
P1 P49135 XPB_MOUSE ATP-dependent 3′–5′-DNA helicase, a component of the core-TFIIH basal transcription factor, involved in nucleotide excision repair of DNA and, when complexed to CAK (CDK activating kinase where CDK stands for cyclin-dependent kinase), in RNA transcription by RNA polymerase II. Acts by opening DNA either around the RNA transcription start site or the DNA damage. 6.8 89127
P2 P97302 BAC1_MOUSE Transcriptional regulator that acts as repressor or activator. Binds in vitro to NF-E2 (nuclear transcription factor erythroid 2) binding sites. Plays important roles in co-ordinating transcription activation and repression by MAFK (musculoaponeurotic fibrosarcoma protein K). 4.9 81375
P3 Q15582 BGH3_HUMAN BetaIG-H3. 7.6 74682
P4 O89091 TIEG-1_MOUSE Transcriptional repressor involved in the regulation of cell growth. Inhibits cell growth. 9.0 51756
P5 O88685 PRSA_MOUSE TBP-1. The 26 S protease is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependence and substrate specificity to the 26 S complex (by similarity). 5.1 49493
P6 Q9JIW5 SMA9_MOUSE Mother against decapentaplegic Smad 8. Transcriptional modulator activated by BMP type 1 receptor kinase. Is a receptor-regulated Smad (R-Smad). 8.7 48314
P7 P70689 CXB6_MOUSE Connexin 30 8.7 30367
P8 P50540 MXI1_MOUSE Transcriptional repressor. MXI1 binds with MAX to form a sequence-specific DNA-binding protein complex that recognizes the core sequence 5′-CAC[GA]TG-3′. MXI1 thus antagonizes MYC transcriptional activity by competing for MAX. 6.8 25978
