Protein attributes

Sequence length	248 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Required in Raf-dependent cell proliferation and photoreceptor differentiation during eye development. Acts upstream of Raf and downstream of Ras, and is essential for viability. Acts as a negative regulator by decreasing its voltage sensitivity. Ref.7
Subunit structure	Homodimer; homodimerization is not essential for modulating the activity of Slo. Interacts with phosphorylated Slob; the interaction with Slob mediates an indirect interaction with Slo. Ref.7 Ref.8
Subcellular location	Cytoplasm By similarity.
Tissue specificity	Predominantly expressed in the ventral nerve cord of the embryo, and in the neural tissues of the head. Also found in the region posterior to the morphogenetic furrow of the eye imaginal disk where cells differentiate as photoreceptors.
Developmental stage	Expressed throughout all stages of embryonic and larval development.
Sequence similarities	Belongs to the 14-3-3 family.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform VI (identifier: P29310-1) Also known as: D; J; This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform VI' (identifier: P29310-2) Also known as: A; G; H; I; The sequence of this isoform differs from the canonical sequence as follows:      149-161: QTAYQDAFDISKG → KNAYQEAFDIAKT
Isoform C (identifier: P29310-3) The sequence of this isoform differs from the canonical sequence as follows:      146-161: DDSQTAYQDAFDISKG → EDSKKAYQEAFDIAKT      185-193: LNSPDKACQ → INSPARACH
Note: No experimental confirmation available.
