Sina is a RING-type E3 ubiquitin ligase first identified in Drosophila, a protein essential for the determination of the R7 pathway in photoreceptor cell development [3]. Murine and human homologues of Sina have also been identified, namely Siah1 and Siah2 [1-4], and also in Arabidopsis, SINAT3 [5]. These proteins have a RING-type zinc finger at the N-terminal followed by two zinc fingers and a C-terminal TRAF-like domain (Pfam:PF03145) [1-5]. This entry represents the central C2H2 zinc finger domains.	Domain
A	PF21362	E3 ubiquitin-protein ligase sina/sinah, RING finger (Sina_RING)	E3 ubiquitin-protein ligase sina/sinah, RING finger	This is the RING finger domain of Sina and its homologues from animals, Sinah1/2 and plants, such as SINAT3 from Arabidopsis [3].

This is the RING finger domain of Sina and its homologues from animals, Sinah1/2 and plants, such as SINAT3 from Arabidopsis [3]. Sina (seven in absentia) was first identified in Drosophila and is essential for the determination of the R7 pathway in photoreceptor cell development. It consists of a RING zinc finger at the N-terminal, followed by two zinc finger (C2H2 type) domains (Pfam:PF21361) and a C-terminal TRAF-like domain (Pfam:PF03145) [1,2]. This domain gives the E3 ubiquitin ligase activity to these proteins.	Domain
