In this paper we consider all possible consistent extensions of
the $AdS_5xS^5$ superalgebra, $psu(2,2|4)$, to incorporate brane
charges by introducing both bosonic and fermionic (non)central
extensions. We study the Inonu-Wigner contraction of the extended
$psu(2,2|4)$ under the Penrose limit to obtain the most general
consistent extension of the plane-wave superalgebra and compare
these extensions with the possible BPS (flat or spherical) brane
configurations in the plane-wave background. We give an explicit
realization of these extensions in terms of the Tiny Graviton
Matrix Theory (TGMT) [hep-th/0406214] which is the 0+1 dimensional
gauge theory conjectured to describe the DLCQ of strings on the
$AdS_5xS^5$ and/or the plane-wave background.
