Basic Parts
BBa_K3506007 is the promoter of the G2/mitotic-specific Cyclin-B2 encoding gene (CLB2) which initiates its transcription in late S and G2/M in the yeast cell cycle. This part is used to control the periodic expression of Cas9 so that we can couple the expression of Cas9 to cell division.
BBa_K3506010 is the first 124 amino acids of Cyclin B2 in Saccharomyces cerevisiae. It functions as a degradation tag and promotes the degradation of Clb2 protein.
BBa_K3506021 is an RNA polymerase III promoter and is a common part of eukaryotic expression systems. We use it to initiate the transcription of hgRNA.
BBa_K3506050 is a single guide RNA that guides Cas9 to target ADE2 gene in Cryptococcus neoformans.

Inducible double promoter module
BBa_K3506009 consists of two parts: CLB2 promoter (BBa_K3506007) and Cas9 (BBa_K2130013). This part enables the CLB2 promoter to initiate the expression of Cas9, so as to achieve the goal of coupling the expression of Cas9 with the cell cycle.
BBa_K3506030 consists of four parts: CLB2 promoter (BBa_K3506007), the first 124 amino acids of Clb2 (BBa_K3506010), a linker (BBa_K3506008) and Cas9 (BBa_K2130013). CLB2 promoter initiates the expression of Cas9 at S phase. The first 124 amino acids of Clb2 degrades Cas9 quickly. By this way, we control the expression and degradation of Cas9 periodically.
BBa_K3506036 consists of three parts: Clb2 124aa (BBa_K3506010) and GFP (BBa_E0040) through Linker (BBa_K3506013). It is designed to characterize the degradation rate of Clb2 N124aa.
BBa_K3506095 consists of two parts: GAPDH promoter (BBa_K3506099) and U6 promoter (BBa_K3506021). It is used to read the lineage tracing information at RNA level at specific time.
BBa_K3506022 consists of two parts: GAL7 promoter (BBa_K3506424) and U6 promoter (BBa_K3506021). It is used to read the lineage tracing information at RNA level at specific time.
