MEMORANDUM2

Irving Sheppard, a California state prisoner, appeals pro se the district court’s summary judgment for defendants in his 42 U.S.C. § 1983 action alleging various constitutional violations in connection with prison disciplinary actions. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo, see Barnett v. Centoni, 31 F.3d 813, 815 (9th Cir. 1994) (per curiam), and we affirm.

Without deciding whether Sheppard’s complaint provided defendants with fair notice of a retaliation claim, we affirm the district court’s dismissal of this claim because Sheppard was unable to establish that he was engaging in constitutionally protected conduct when refusing to serve as an informant. See id. at 816.

We also affirm the district court’s summary judgment for defendants on Shep*575pard’s due process claims. See Sandin v. Conner, 515 U.S. 472, 483-84, 115 S.Ct. 2293, 132 L.Ed.2d 418 (1995); Zimmerlee v. Keeney, 831 F.2d 183, 186-87 (9th Cir. 1987) (per curiam).

Because Sheppard failed to provide any evidence regarding his race discrimination and cruel and unusual punishment claims, we affirm the district court’s summary judgment for defendants on these claims. See Celotex Corp. v. Catrett, 477 U.S. 317, 322-23, 106 S.Ct. 2548, 91 L.Ed.2d 265 (1986).

We deny all pending motions.

AFFIRMED.
