Let
ℳ
be an
n
-cluster tilting subcategory of mod-Λ, where Λ is an Artin algebra. Let
S
(
ℳ
)
denote the full subcategory of
S
(
Λ
)
, the submodule category of Λ, consisting of all the monomorphisms in
ℳ
. We construct two functors from
S
(
ℳ
)
to
mod
−
ℳ
¯
, the category of finitely presented additive contravariant functors on the stable category of
ℳ
. We show that these functors are full, dense and objective and hence provide equivalences between the quotient categories of
S
(
ℳ
)
and
mod
−
ℳ
¯
. We also compare these two functors and show that they differ by the
n
-th syzygy functor, provided
ℳ
is an
n
ℤ-cluster tilting subcategory. These functors can be considered as higher versions of the two functors studied by Ringel and Zhang (2014) in the case
Λ
=
k

and generalized later by Eiríksson (2017) to self-injective Artin algebras. Several applications are provided.
