Calcineurin-responsive transcription factor gene transcriptions

# Human genes
Gene ID: 1827 is RCAN1 regulator of calcineurin 1 on 21q22.12: "The protein encoded by this gene interacts with calcineurin A and inhibits calcineurin-dependent signaling pathways, possibly affecting central nervous system development. This gene is located in the minimal candidate region for the Down syndrome phenotype, and is overexpressed in the brain of Down syndrome fetuses. Chronic overexpression of this gene may lead to neurofibrillary tangles such as those associated with Alzheimer disease. Alternative splicing results in multiple transcript variants."
- NP_001272318.1 calcipressin-1 isoform d: "Transcript Variant: This variant (4) uses an alternate 5' exon compared to variant 1. The resulting isoform (d) has a distinct N-terminus compared to isoform a."
- NP_001272320.2 calcipressin-1 isoform e: "Transcript Variant: This variant (5) uses an alternate promoter and 5' exon compared to variant 1. The resulting isoform (e) has a distinct N-terminus compared to isoform a."
- NP_001272321.1 calcipressin-1 isoform b: "Transcript Variant: This variant (6) uses an alternate promoter and 5' exon compared to variant 1. The resulting isoform (b) has a shorter N-terminus compared to isoform a."

- NP_981963.1 calcipressin-1 isoform c: "Transcript Variant: This variant (3) uses an alternate 5' exon compared to variant 1. The resulting isoform (c) has a distinct N-terminus compared to isoform a."

# Interactions

# Consensus sequences
The upstream activating sequence for the calcineurin-responsive transcription factor (Crz1p) is 5'-TG(A/C)GCCNC-3'.

# Hypotheses
- A1BG has no Calcineurin-responsive transcription factors in either promoter.
- A1BG is not transcribed by a Calcineurin-responsive transcription factor.
- Calcineurin-responsive transcription factor does not participate in the transcription of A1BG.

# CRT samplings
Copying 5'-TGCGCCCC-3' in "F" yields none between ZSCAN22 and A1BG and none between ZNF497 and A1BG as can be found by the computer programs.

# Calcineurin-responsive transcription factor analysis and results
The upstream activating sequence for the calcineurin-responsive transcription factor (Crz1p) is 5'-TG(A/C)GCCNC-3'.
Comparison:
The occurrences of real CRTs are greater than the randoms. This suggests that the real CRTs are likely active or activable.
