TABLE 1.

Transcript variant and isoform of SIN1.

Transcript variant	Synonyms	Isoform	Nt a	AA b		CCDS c
1	SIN1	1.1	3369	522	Canonical isoform	CCDS35140.1
2	SIN1 beta	1.2	1461	486	Lacks an alternate in‐frame exon in the 3′ coding region, compared to variant 1.	CCDS6864.1
3	SIN1 gamma	1.3	1428	475	Lacks an alternate in‐frame exon in the 3′ coding region, compared to variant 1	CCDS35139.1
4	SIN1 delta	1.4	993	330	Has a shorter N‐terminus, compared to isoform 1. The existence of this isoform has not been confirmed experimentally. Variants 4 and 5 encode the same isoform.	CCDS35141.1
5	SIN1 epsilon	1.4	993	330	Also known as SIN1e, lacks two alternate in‐frame exons in the 5′ coding region, and uses a downstream start codon, compared to variant 1. The resulting protein (isoform 4), also known as the delta isoform, has a shorter N‐terminus, compared to isoform 1. The existence of this isoform has not been confirmed experimentally. Variants 4 and 5 encode the same isoform.	CCDS35141.1
6	SIN1 alpha	1.5	972	323	Differs in the 3′ coding region and UTR, compared to variant 1	CCDS48020.1
