**Title: Determining the Membrane Localization Sequence of Mira Protein**

The images below are confocal images of cells expressing the full-length Mira protein (Mira 1-830), which localizes to the plasma membrane. The images also include truncations of the Mira protein that localize either to the plasma membrane and/or the nucleus. The primary objective here is to determine the sufficiency of the membrane localization sequence of Mira.

**Diagram Description:**

A series of confocal images are labeled A through H:

- **A (Mira 1-830):** Displays the full-length Mira protein, showing localization at the plasma membrane.
- **B (Mira 1-727):** Shows a truncation of the protein, localizing similarly to the full-length protein.
- **C (Mira 1-648):** Another truncation indicating similar localization.
- **D (Mira 1-465):** Depicts further truncation, with localization primarily at the plasma membrane.
- **E (Mira 1-329):** Shows localization changes, potentially to both the plasma membrane and other areas.
- **F (Mira 1-280):** Indicates nuclear localization for this truncation.
- **G (Mira 1-106):** Primarily nuclear localization is observed.
- **H (Mira 94-290):** Exhibits distinct localization, differing from the others.

**Options to Determine Membrane Localization Sequence Sufficiency:**

1. Remove amino acids 94-290 from Mira and examine the localization of the protein.
2. Remove amino acids 1-106 from Mira and examine the localization of the protein.
3. Add amino acids 1-830 from Mira to GFP and examine localization of GFP.
4. Add amino acids 94-290 from Mira to GFP and examine localization of GFP.
5. Add amino acids 1-106 from Mira to GFP and examine localization of GFP.

Using these experimental approaches, one can assess the sequences necessary for proper membrane localization of the Mira protein.
